THE IDEAL CAPACITOR
The non-ideal characteristics of a real capacitor can be
ignored at low frequencies. Physical size imparts inductance
to the capacitor and dielectric and metal electrodes result in
resistive losses, but these often are of negligible effect on the
circuit. At the very high frequencies of radio communication
(>100MHz) and satellite systems (>1GHz), these effects
become important. Recognizing that a real capacitor will
exhibit inductive and resistive impedances in addition to
capacitance, the ideal capacitor for these high frequencies is
an ultra low loss component which can be fully characterized
in all parameters with total repeatability from unit to unit.
Until recently, most high frequency/microwave capacitors
were based on fired-ceramic (porcelain) technology. Layers
of ceramic dielectric material and metal alloy electrode paste
are interleaved and then sintered in a high temperature oven.
This technology exhibits component variability in dielectric
quality (losses, dielectric constant and insulation resistance),
variability in electrode conductivity and variability in physical
size (affecting inductance). An alternate thin-film technology
has been developed which virtually eliminates these vari-
ances. It is this technology which has been fully incorporated
into Accu-P®and Accu-P® to provide high frequency capaci-
tors exhibiting truly ideal characteristics.
The main features of Accu-P®may be summarized as follows:
• High purity of electrodes for very low and repeatable
ESR.
• Highly pure, low-K dielectric for high breakdown field,
high insulation resistance and low losses to frequencies
above 40GHz.
• Very tight dimensional control for uniform inductance,
unit to unit.
• Very tight capacitance tolerances for high frequency
signal applications.
This accuracy sets apart these Thin-Film capacitors from
ceramic capacitors so that the term Accu has been
employed as the designation for this series of devices, an
abbreviation for “accurate.”
THIN-FILM TECHNOLOGY
Thin-film technology is commonly used in producing semi-
conductor devices. In the last two decades, this technology
has developed tremendously, both in performance and in
process control. Today’s techniques enable line definitions of
below 1μm, and the controlling of thickness of layers at 100Å
(10-2μm). Applying this technology to the manufacture of
capacitors has enabled the development of components
where both electrical and physical properties can be tightly
controlled.
The thin-film production facilities at AVX consist of:
• Class 1000 clean rooms, with working areas under
laminar-flow hoods of class 100, (below 100 particles
per cubic foot larger than 0.5μm).
• High vacuum metal deposition systems for high-purity
electrode construction.
• Photolithography equipment for line definition down to
2.0μm accuracy.
• Plasma-enhanced CVD for various dielectric deposi-
tions (CVD=Chemical Vapor Deposition).
• High accuracy, microprocessor-controlled dicing saws
for chip separation.
• High speed, high accuracy sorting to ensure strict
tolerance adherence.

Thin-Film Chip Capacitors
ACCU-P®TECHNOLOGY
The use of very low-loss dielectric materials, silicon dioxide and
silicon oxynitride, in conjunction with highly conductive elec-
trode metals results in low ESR and high Q. These
high-frequency characteristics change at a slower rate with
increasing frequency than for ceramic microwave capacitors.
Because of the thin-film technology, the above-mentioned
frequency characteristics are obtained without significant
compromise of properties required for surface mounting.
The main Accu-P®properties are:
• Internationally agreed sizes with excellent dimensional
control.
• Ultra small size chip capacitors (01005) are available.
• Ultra tight capacitance tolerances.
• Low ESR at VHF, UHF and microwave frequencies.
• Enhanced RF power handling capablity.
• High stability with respect to time, temperature, frequency
and voltage variation.
• Nickel/solder-coated terminations to provide excellent sol-
derability and leach resistance.
ACCU-P®FEATURES
Accu-P®meets the fast-growing demand for low-loss
(high-Q) capacitors for use in surface mount technology espe-
cially for the mobile communications market, such as cellular
radio of 450 and 900 MHz, UHF walkie-talkies, UHF cordless
telephones to 2.3 GHz, low noise blocks at 11-12.5 GHz and
for other VHF, UHF and microwave applications.
Accu-P®is currently unique in its ability to offer very
low capacitance values (0.05pF) and very tight capacitance
tolerances (±0.01pF).
• The RF power handling capability of the Accu-P®allows
for its usage in both small signal and RF power applica-
tions.
• Thin Film Technology guarantees minimal batch to batch
variability of parameters at high frequency.
• Inspection test and quality control procedures in accor-
dance with ISO 9001, CECC, IECQ and USA MIL
Standards yield products of the highest quality.
• Hand soldering Accu-P®: Due to their construction utilizing
relatively high thermal conductivity materials, Accu-P’s
have become the preferred device in R & D labs and pro-
duction environments where hand soldering is used.

Accu-P®
Environmental / Mechanical Characteristics
QUALITY & RELIABILITY
Accu-P®is based on well established thin-film technology
and materials.
• ON-LINE PROCESS CONTROL
This program forms an integral part of the production cycle
and acts as a feedback system to regulate and control
production processes. The test procedures, which are
integrated into the production process, were developed
after long research work and are based on the highly
developed semiconductor industry test procedures and
equipment. These measures help AVX to produce a con-
sistent and high yield line of products.
• FINAL QUALITY INSPECTION
Finished parts are tested for standard electrical parameters
and visual/mechanical characteristics. Each production lot
is 100% evaluated for: capacitance and proof voltage at
2.5 UR. In addition, production is periodically evaluated for:
Average capacitance with histogram printout for
capacitance distribution;
IR and Breakdown Voltage distribution;
Temperature Coefficient;
Solderability;
Dimensional, mechanical and temperature stability.
QUALITY ASSURANCE
The reliability of these thin-film chip capacitors has been
studied intensively for several years. Various measures
have been taken to obtain the high reliability required today
by the industry. Quality assurance policy is based on well
established international industry standards. The reliability
of the capacitors is determined by accelerated testing

ADVANTAGES OF ACCU-P®
IN RF POWER CIRCUITS
The optimized design of Accu-P®offers the designer of RF
power circuits the following advantages:
• Reduced power losses due to the inherently low ESR of
Accu-P®.
• Increased power dissipation due to the high thermal
conductivity of Accu-P®.
PRACTICAL APPLICATION
IN RF POWER CIRCUITS
• There is a wide variety of different experimental methods
for measuring the power handling performance of a
capacitor in RF power circuits. Each method has its
own problems and few of them exactly reproduce the
conditions present in “real” circuit applications.
• Similarly, there is a very wide range of different circuit appli-
cations, all with their unique characteristics and operating
conditions which cannot possibly be covered by such
“theoretical” testing.
• THE ONLY TRUE TEST OF A CAPACITOR IN ANY PARTICULAR
APPLICATION IS ITS PERFORMANCE UNDER OPERATING
CONDITIONS IN THE ACTUAL CIRCUIT.
Accu-P®
Performance Characteristics RF Power Applications
RF POWER APPLICATIONS
In RF power applications capacitor losses generate heat. Two
factors of particular importance to designers are:
• Minimizing the generation of heat.
• Dissipating heat as efficiently as possible.
CAPACITOR HEATING
• The major source of heat generation in a capacitor in RF
power applications is a function of RF current (I) and ESR,
from the relationship:
Power dissipation = I2
RMS x ESR
• Accu-P®capacitors are specially designed to minimize
ESR and therefore RF heating. Values of ESR for
Accu-P®capacitors are significantly less than those of
ceramic MLC components currently available.
HEAT DISSIPATION
• Heat is dissipated from a capacitor through a variety of
paths, but the key factor in the removal of heat is the
thermal conductivity of the capacitor material.
• The higher the thermal conductivity of the capacitor, the
more rapidly heat will be dissipated.
• The table below illustrates the importance of thermal
conductivity to the performance of Accu-P®in power
applications.

Application Notes
GENERAL
Accu-P®SMD capacitors are designed for soldering to printed
circuit boards or other substrates. The construction of the
components is such that they will withstand the time/temper-
ature profiles used in both wave and reflow soldering meth-
ods.
CIRCUIT BOARD TYPE
The circuit board types which may be used with Accu-P®are
as follows:
All flexible types of circuit boards
(eg. FR-4, G-10) and also alumina.
For other circuit board materials, please consult factory.
HANDLING
SMD capacitors should be handled with care to avoid damage
or contamination from perspiration and skin oils. The use of
plastic tipped tweezers or vacuum pick-ups is strongly recom-
mended for individual components. Bulk handling should
ensure that abrasion and mechanical shock are minimized. For
automatic equipment, taped and reeled product gives the
ideal medium for direct presentation to the placement
machine.
COMPONENT PAD DESIGN
Component pads must be designed to achieve good
joints and minimize component movement during reflow
soldering. Pad designs are given below for both wave and
reflow soldering.
The basis of these designs is:
a. Pad width equal to component width. It is permissible to
decrease this to as low as 85% of component width but
it is not advisable to go below this.
b. Pad overlap 0.5mm beneath large components. Pad
overlap about 0.3mm beneath small components.
c. Pad extension of 0.5mm for reflow of large components
and pad extension about 0.3mm for reflow of small com-
ponents. Pad extension about 1.0mm for wave soldering.

Application Notes
PREHEAT & SOLDERING
The rate of preheat in production should not exceed 4°C/
second and a recommended maximum is about 2°C/second.
Temperature differential from preheat to soldering should not
exceed 100°C.
For further specific application or process advice, please consult
AVX.
COOLING
After soldering, the assembly should preferably be allowed
to cool naturally. In the event of assisted cooling, similar
conditions to those recommended for preheating should be
used.
HAND SOLDERING & REWORK
Hand soldering is permissible. Preheat of the PCB to 150°C is
required. The most preferable technique is to use hot air sol-
dering tools. Where a soldering iron is used, a temperature
controlled model not exceeding 30 watts should be used and
set to not more than 260°C.
CLEANING RECOMMENDATIONS
Care should be taken to ensure that the devices are
thoroughly cleaned of flux residues, especially the space
beneath the device. Such residues may otherwise become
conductive and effectively offer a lossy bypass to the device.
Various recommended cleaning conditions (which must be
optimized for the flux system being used) are as follows:
Cleaning liquids. . . . . . . i-propanol, ethanol, acetylacetone,
water and other standard PCB
cleaning liquids.
Ultrasonic conditions . . power-20w/liter max.
frequency-20kHz to 45kHz.
Temperature . . . . . . . . . 80°C maximum (if not otherwise
limited by chosen solvent system).
Time . . . . . . . . . . . . . . . 5 minutes max.
STORAGE CONDITIONS
Recommended storage conditions for Accu-P®prior to use
are as follows:
Temperature . . . . . . . . . . 15°C to 35°C
Humidity . . . . . . . . . . . . . ≤65%
Air Pressure . . . . . . . . . . 860mbar to 1060mbar
