Notes

Please consider 'Notice (Rating).'
When rated current is applied to the products, inductance will be within ±30% of nominal inductance.
Keep the temperature (ambient temperature plus self-generation of heat) under 125°C.
When rated current is applied to the products, the temperature rise caused by self-generated heat shall be limited to 40°C max.
Rated current is derated as following figure depending on the operating temperature.
