E/H (Military M/D55342)
Vishay Thin Film
QPL MIL-PRF-55342 Qualified Thin Film Resistor Chips
FEATURES
• Established reliability, “R” failure rate level (100 ppm), C = 2
SURFACE MOUNT
CHIPS
• High purity alumina substrate 99.6 % purity
• 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
(< - 25 dB, 0.5 ppm/V)
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.
