 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50s 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 1. Usage, transport and storage 

conditions in NOTES.
