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 1.250s 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.
*4. Allowable temperature range with our package form: 40C to +60C 40F to +140F.
