Military Established Reliability Bulk Metal Foil Technology RNC90Y and RNC90Z (Z-Foil) to MIL-PRF-55182/9 FEATURES QPL product with established reliability (ER) R level high reliability resistor qualified to MIL-PRF-55182/9 Load life stability: 0.05 % R for 2000 h, 0.3 W at + 125 C Temperature coefficient of resistance (TCR): 2 ppm/C max. (- 55 C to + 175 C) Resistance tolerance: to 0.005 % Thermal EMF: < 0.1 V/C Qualified resistance range: 4.99 to 121 k (RNC90Y) 30.1 to 121 k(RNC90Z) INTRODUCTION Specially conditioned non-QPL resistors available Military Established Reliability resistors from Vishay Foil See data sheet Improved Performance Tested Resistors (VFR) are available in resistance values from Fast thermal stabilization 4.99 through 121 k and with tolerances from 0.005% to Electrostatic discharge (ESD) above 25 000 V 1.0%. The same resistors are also available as Non inductive, non capacitive design non-qualified products for customers desiring higher or lower Current noise < - 42 dB resistance values and the same or better performance Prototype sample available 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 55C to +175C is a significant improvement over the existing RNC90Y specification. The RNC90Z is a direct replacement for the RNC90Y.
