Vishay Thin Film
QPL MIL-PRF-55342 Qualified Thin Film Resistor Chips
FEATURES
• Established reliability, “R” failure rate level
• High purity alumina substrate for high power
• Wraparound termination featuring a tenacious adhesion
layer covered with an electroplated nickel barrier layer for
+ 150 °C operating conditions
Actual Size
M55342/02
• Very low noise and voltage coefficient
• Non-inductive
• Laser-trimmed tolerances to ± 0.1 %
• Wraparound resistance less than 0.010 ohms typical
• In-lot tracking less than 5 ppm/°C
Thin Film Mil chip resistors feature all sputtered wraparound
termination for excellent adhesion and dimensional uniformity.
They are ideal in applications requiring stringent performance
requirements. Established reliability is assured through
100 % screening and extensive environmental lot testing.
Wafer is sawed producing exact dimensions and clean,
straight edges.
• Complete MIL-testing available in-house
• Antistatic waffle pack or tape and reel packaging available
NOTE: Specification changed by DSCC from MIL-R-55342
to MIL-PRF-55342.
