Flat Chip Resistors combine the proven reliability of the
professional products with an advanced level of precision
and stability. Therefore they are perfectly suited for
applications in the fields of test and measuring equipment
together with industrial and medical electronics.
Note
1. The power dissipation on the resistor generates a temperature rise against the local ambient, depending on the heat flow support of the
printed-circuit board (thermal resistance). The rated dissipation applies only if the permitted film temperature is not exceeded.

Precision Flat Chip Resistors
Vishay Beyschlag
DESCRIPTION
Production is strictly controlled and follows an extensive set
of instructions established for reproducibility. A
homogeneous film of metal alloy is deposited on a super high
grade (96 % Al
2
03) ceramic substrate and conditioned to
achieve the desired temperature coefficient. Specially
designed inner contacts are deposited on both sides. A
special laser is used to achieve the target value by smoothly
fine trimming the resistive layer without damaging the
ceramics. A further conditioning is applied in order to
stabilize the trimming result. The resistor elements are
covered by a blue protective coating designed for electrical,
mechanical and climatic protection. The terminations receive
a final pure tin on nickel plating.
The result of the determined production is verified by an
extensive testing procedure and optical inspection
performed on 100 % of the individual chip resistors. Only
accepted products are laid directly into the paper tape in
accordance with EN 60286-3.
ASSEMBLY
The resistors are suitable for processing on automatic SMD
assembly systems and for automatic soldering using wave,
reflow or vapour phase. The encapsulation is resistant to all
cleaning solvents commonly used in the electronics industry,
including alcohols, esters and aqueous solutions. The
resistors are lead (Pb)-free, the pure tin plating provides
compatibility with lead (Pb)-free and lead-containing
soldering processes. The immunity of the plating against tin
whisker growth has been proven under extensive testing. All
products comply with the CEFIC-EECA-EICTA list of legal
restrictions on hazardous substances.
This includes full compatibility with the following directives:
2000/53/EC End of Vehicle life Directive (ELV)
2000/53/EC Annex II to End of Vehicle Life Directive (ELV II)
2002/95/EC Restriction of the use of Hazardous
Substances Directive (RoHS)
2002/96/EC Waste Electrical and Electronic Equipment
Directive (WEEE)
Solderability is specified for 2 years after production or
re-qualification. The permitted storage time is 20 years.
APPROVALS
The resistors are tested in accordance with EN 140401-801
(superseding CECC 40401-801) which refers to EN 60115-1
and EN 140400. Approval of conformity is indicated by the
CECC logo on the package label.
Vishay BEYSCHLAG has achieved "Approval of
Manufacturer" in accordance with EN 100114-1. The
release certificate for "Technology Approval Schedule" in
accordance with CECC 240001 based on EN 100114-6 is
granted for the Vishay BEYSCHLAG manufacturing process.
SPECIALS
On request, resistors are available with established reliability
in accordance with EN 140 401-801 Version E. Please refer
to the special data sheet for information on failure rate level,
available resistance ranges and order codes.

ORDERING INFORMATION
Components may be ordered by using either a simple clear
text ordering code, see “Type description and ordering code”
or Vishay BCcomponents’ unique 12NC.
Numeric Ordering Code (12NC)
The resistors have a 12-digit ordering code starting with
2312.
The subsequent 4 digits indicate the resistor type,
specification and packaging; see the 12NC Ordering Code
table.
The remaining 4 digits indicate the resistance value:
- The first 3 digits indicate the resistance value.
- The last digit indicates the resistance decade in
accordance with the 12NC Indicating Resistance Decade
table.
Last Digit of 12NC Indicating Resistance Decade
Ordering Example
The ordering code of a MCT 0603 resistor, value 47 k and
TC 25 with ± 0.1 % tolerance, supplied in cardboard tape of
5000 units per reel is: 2312 216 74703.
