1Ω ~ 91KΩ is 0 ~ -450ppm/°C; 100KΩ ~ 1MΩ is 0 ~ -700ppm/°C; 1.1MΩ ~ 10MΩ is -800 ~ -700ppm/°C
Test methods: natural resistance change per temp. °C; [R
temp. (t
No evidence of flashover mechanical damage, arcing 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.
±1% +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.
For normal type: <100KΩ is ±3%, ≥100KΩ is ±5%. For flame retardant type: <100KΩ is ±5%, ≥100KΩ is ±10%.
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.
For normal type: <56KΩ is ±2%, ≥56KΩ is ±3%. For flame retardant type: <100KΩ is ±5%, ≥100KΩ is ±10%. 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.
10,000MΩ min. Test method is resistors are clamped in the trough of a 90° metallic V-block and tested at the maxi-
mum overload voltage for 60 +10/-0 seconds.
±1% +0.05Ω max. with no evidence of mechanical damage. Test method is leads are immersed 3.2~4.8mm from
the body in 350°C ±10°C solder for 3 ±0.5 seconds
