ASCTB191E 201202-T

2. Specifications

Notes: *1. This value can change due to the switching frequency, environmental conditions, and desired reliability level, therefore it is recommended to check this with the

actual load.

*2. Wave is standard shock voltage of

±1.2×50µs according to JEC-212-1981

*3. The upper limit of the ambient temperature is the maximum temperature that can satisfy the coil temperature rise value. Refer to Usage, transport and storage

conditions in NOTES.
