±50ppm/°C standard (±15ppm/°C, ±25ppm/°C, ±100ppm/°C, and ±200ppm/°C available upon special request).
Test methods: natural resistance change per temp. °C; [R
temp. (t
No evidence of flashover mechanical damage, arching or insulation breakdown. Test method is resistors are
clamped in the trough of a 90° metallic V-block and tested at the maximum overload voltage for 60 +10/-0 seconds.
±1% +0.05Ω max. with no evidence of mechanical damage. Test method is five cycles for duty cycle as follows:
step 1 at -55°C ±3°C for 30 min.; step 2 at room temp. for 10~15 min.; step 3 at +155°C ±2°C for 30 min.; step 4 at
room temp. for 10~15 min.
±0.5% +0.05Ω max. with no evidence of mechanical damage. Test method is the application of a potential of 2.5
times RCWV for 5 seconds.
±1% +0.05Ω max. with no evidence of mechanical damage. Test method is 1,000 cycles operating at 4 times RCWV
with duty cycle of 1 second "on", 25 seconds "off".
±2% +0.05Ω max. with no evidence of mechanical damage. Test method is 240 hours exposure in a humidity test
chamber controlled at 40°C ±2°C and 90~95% relative humidity.
±5% +0.05Ω max. with no evidence of mechanical damage. Test method is 1,000 hours operating at RCWV with
duty cycle of 1.5 hours "on", 0.5 hour "off" in a humidity test chamber controlled at 40°C ±2°C and 90~95% relative
humidity.
±5% +0.05Ω max. with no evidence of mechanical damage. Test method is 1,000 hours operating at RCWV with
duty cycle of 1.5 hours "on", 0.5 hour "off" at +70°C ±2°C ambient.
No evidence of mechanical damage. Test methods as follows: Direct Load; resistance to a 2.5kg direct load for 10
seconds in direction of longitudinal axis of the terminal leads. Twist Test; terminal leads are bent through 90° at a
point of about 6mm from the body of the resistor and are rotated through 360° about the original axis of the bent ter-
minal in alternating direction for a total of 3 rotations.
95% coverage min. Test method is that the area is covered with a new, smooth, clean, shiny and continuous surface
free from concentrated pinholes. Test temperature of solder is +235°C ±5°C. Time in solder is 3 +.5/-0 seconds.
No deterioration of protective coating and markings. Test method is that the resistors are immersed in a bath of tri-
choethane completely for 3 minutes with ultrasonic.
