rated voltage; then OFF: 30 min.
2. Perform 1,000 hours cyclically
1. Dwell in humidity chamber at 40 ±2°C and 95% RH for
ON: 90 min. at rated voltage; then OFF: 30 min.
2. Perform 1.,000 hours cyclically
1. -55±3°C~125±3°C, make 5 cycles.
2. Released 1 hour in room temp., then measure value.
1. Immersed in molten solder at 270±5°C for 10±.01 sec.
2.Released 1 hour in room temp., then measure value.
1. Immersed in rosin solution for 5~10 seconds.
2. Re-immersed in solder pot at 230±5°C for 3±0.5 sec
1. Perform 10,000 voltage cycles as follows: ON (2.5 x rated
voltage or current) 1 sec. and OFF 25 sec.
2. Released 30 min. without loading.
3. Measure resistance.
Apply 300VAC for 1 second
Apply 100VDC.
