+ Custom R-Value on Request.
++ high voltage energy products voulunerble by a lot of factors , so would better use small q'ty as an order first and get test results, place main order
• Pulse width shall be less than 10 ㎲ at 1R ~ 20kΩ ,and less than 10ms at 22kΩ~2MΩ
1) less than 10 ㎲ pulse width, limited by allowable power rating
2) continous pulsing or dc , ac, they are limited by allowable power rating
