Military and Space Established Reliability Vishay Foil Resistors Bulk Metal Foil Technology RNC90Y and RNC90Z (Z-Foil) to MIL-PRF-55182/9 FEATURES QPL product with established reliability (ER): meets requirements of MIL-PRF-55182/9 Load life stability: 0.005 % 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) INTRODUCTION 30.1 to 121 k (RNC90Z) Vishay Military Established Reliability resistors are available Specially conditioned non-QPL resistors available in resistance values from 4.99 through 121 k and for See data sheet Improved Performance Tested tolerances from 0.005 % to 1.0 %. The same resistors are Fast thermal stabilization also available as a non-qualified product for customers Rise time: 1 ns without ringing desiring higher or lower resistance values and the same or Special coatings that provide a cushioning layer which isolates better performance capabilities. (See table 2) Both the the resistive element from external stresses and moisture qualified and the non-qualified version are manufactured on Electrostatic discharge (ESD) above 25 000 V the same production line facilities and are subjected to the Non inductive, non capacitive design same process, lot control, conditioning, and GRP A (100 %) Current noise < - 42 dB screening. Qualified versions receive additional MIL Group B Prototype sample available from 72 h and C testing.
