RATING
1. Coil data
Notes: *1. Square, pulse drive
*2. Maximum allowable voltage is the maximum voltage which can satisfy the coil temperature rise value.
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.
3. Expected electrical life
Condition: Resistive, at 20 times/min.
