Q 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 1. Usage, transport and storage
conditions in NOTES.
