Note
(1) Please refer to APPLICATION INFORMATION below.
APPLICATION INFORMATION
When the resistor dissipates power, a temperature rise above the ambient temperature occurs, dependent on the thermal
resistance of the assembled resistor together with the printed circuit board. The rated dissipation applies only if the permitted
film temperature is not exceeded.
These resistors do not feature a limited lifetime when operated within the permissible limits. However, resistance value drift
increasing over operating time may result in exceeding a limit acceptable to the specific application, thereby establishing a
functional lifetime.

Note
• The presented operation modes do not refer to different types of resistors, but actually show examples of different loads, that lead to
different film temperatures and different achievable load-life stability (drift) of the resistance value. A suitable low thermal resistance of the
circuit board assembly must be safeguarded in order to maintain the film temperature of the resistors within the specified limits. Please
consider the application note “Thermal Management in Surface-Mounted Resistor Applications” (www.vishay.com/doc?28844) for
information on the general nature of thermal resistance.
Note
• Resistance ranges printed in bold are preferred TCR / tolerance combinations with optimized availability.

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 high
grade ceramic substrate (Al2O3) 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 cutting a
meander groove in the resistive layer without damaging the
ceramics. For the high and low ohmic range, optimized
Cermet products provide comparable properties. The
resistor elements are covered by a 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. This
includes full screening for the elimination of products with
potential risk of early field failures (feasible for R 10 ).
Only accepted products are laid directly into the paper tape
in accordance with IEC 60286-3 Type 1a (1).
ASSEMBLY
The resistors are suitable for processing on automatic SMD
assembly systems. They are suitable for automatic
soldering using wave, reflow or vapor phase as shown in
IEC 61760-1. The encapsulation is resistant to all cleaning
solvents commonly used in the electronics industry,
including alcohols, esters and aqueous solutions. The
suitability of conformal coatings, potting compounds and
their processes, if applied, shall be qualified by appropriate
means to ensure the long-term stability of the whole system.
The resistors are RoHS-compliant, the pure tin plating
provides compatibility with lead (Pb)-free and
lead-containing soldering processes. Solderability is
specified for 2 years after production or requalification. The
permitted storage time is 20 years. The immunity of the
plating against tin whisker growth has been proven under
extensive testing.

HISTORICAL 12NC INFORMATION
• The resistors had a 12-digit numeric code starting with
2312.
• The subsequent 4 digits indicated the resistor type,
specification and packaging; see the 12NC table.
• The remaining 4 digits indicated the resistance value:
- The first 3 digits indicated the resistance value.
- The last digit indicated the resistance decade in
accordance with the last digit of 12NC indicating
resistance decade table.
Last Digit of 12NC Indicating Resistance Decade
Historical 12NC example
The 12NC of a MCT 0603 resistor, value 47 k and TCR 50
with ± 1 % tolerance, supplied in cardboard tape of
5000 units per reel was: 2312 215 14703.
