RESISTOR NETWORK SIL
SPECIFICATION
Short Term Overload
Vibration
∆R/R (1% + 0.05Ω)
After application of 21/2 x rated voltage, or the maximum overload voltage, whichever smaller, for a period of 5
secs. Resistance change to be within specification, with no evidence of arcing, burning or charring.
∆R/R (0.5% + 0.5Ω)
Resistors are to be subjected to vibration of amplitude 0.8mm for 2 hours in each of three mutually
perpendicular directions. The vibration frequency shall be swept from 10 to 55 to 10Hz in 1 minute.
Resistance change to be within specification with no evidence of damage.
Components shall withstand twice their rated voltage for 1 minute applied between termination and substrate. No
evidence of arcing, burning or charring.
Dielectric Strength
Solderability
∆R/R (1% + 0.05Ω)
After dipping at 260°C 5°C for 10 seconds, resistance change to be within specification, with no evidence of
arcing, burning or charring. Terminations shall maintain a minimum of 75% coverage following the procedures of
MIL-STD-202E.
Load Life
∆R/R (2% + 0.05Ω)
After 1000 hours application of the rated voltage with a duty cycle of 11/2 hours ON and 1/2 hour OFF, at
70°C. Resistance change to be within specification, with no evidence of arcing, burning or charring.
∆R/R (2% + 0.05Ω)
Moisture Load
After 1000 hours application of the rated voltage with a duty cycle of 11/2 hours ON and 1/2 hour OFF, at
40°C and 90-95% RH. Resistance change to be within specification, with no evidence of arcing, burning
or charring.
