Note:
Calchip has completed the Lead Free transition. All parts shipped with or without the "customer designator" LF at the end of the part
number will be LeadFree. LeadFree material will still continue to have an LF at the end of the Lot Code and a green RoHS symbol on the
label. Please contact your sales associate if you require nonRoHS material.

Test Methods
Cold: +25°C~-55°C
Hot: +25°C~+125°C
1. Apply 2.5 x rated voltage for 5 sec.
2. Wait 30 minutes
3. Measure resistance value
1. Dwell in chamber at 70±2°C for ON: 90 min. at
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.
