Resistor Material
The resistors shall have a power rating
based on continuous full-load operation
at an ambient temperature of 70°C.
For operation at ambient temperature
in excess of 70°C, the load shall be derated
in accordance with figure of Derating Curve.
Test method JIS C 5202
Measuring temperature
+25°C/ -55°C/ +20°C/ +125°C
2.5 times rated voltage 5 seconds
CRN10: 50Vdc, CRN16/35: 100Vdc
CRN31/32: 500Vdc
Install a sample on the board and bend the board

10Hz → 55Hz → 10Hz
3 directions (X, Y, Z) 2 hours each
Amplitude 1.5mm
Dip into 260°C solder bath for 10 seconds
After dipping into flux, dip into 235°C
solder bath for 2 seconds
Cycle between -55°C and
+150°C for 5 cycles
Rated voltage 1.5 hours “ON” 0.5 hours
“OFF” 40°C, 95% RH 1,000 hours
Rated voltage 1.5 hours “ON” 0.5 hours
