Coil data

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. In accordance with UL class-F

*4. Coil holding voltage is the coil voltage after 100 ms from the applied nominal coil voltage.

*5. 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.
