+ 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

1) less than 10 ㎲ pulse width, limited by allowable power rating

2) continous pulsing or dc , ac, they are limited by allowable power rating
