INTRODUCTION
Military Established Reliability resistors from Vishay Foil
Resistors (VFR) are available in resistance values from
4.99
Ω
through 121 kΩ and with tolerances from ±0.005% to
±1.0%. The same resistors are also available as
non-qualified products for customers desiring higher or lower
resistance values and the same or better performance
capabilities (see Table 2). Both qualified and non-qualified
versions are manufactured on the same production line
facilities and are subjected to the same process, lot control,
conditioning, and GRP A (100%) screening. Qualified
versions receive additional MIL Group B and C testing.
The RNC90Y has been the benchmark for high-precision,
established-reliability discrete resistors since 1982. In 2000,
VFR engineers achieved a technological breakthrough with
the introduction of the commercial ultra-precision, low-TCR
Z201 resistor. This breakthrough allowed for the introduction
of a resistor with very low TCR and an “R” reliability level.
The RNC90Z TCR limit of ±2 ppm/°C over the extended
range of –55°C to +175°C is a significant improvement over
the existing RNC90Y specification.
The RNC90Z is a direct replacement for the RNC90Y.

Formerly “FSCM”
The response of military and non military grade resistors to environmental stresses can be made better by “Improved
Performance Testing” (IPT). The IPT part will see burn-in and cycling that removes the “knee” from the normal drift of non IPT
parts. (See Table 4 for the improvement to expect in military parts when calling for VFR recommended screening). Users should
be aware that IPT testing renders the part non QPL and so a 3XXXXX part number will be assigned by VFR. Consult Applications
Engineering for details and ordering advice.
