*1 When rated current is applied to the products, inductance change will be within ±30% of initial Inductance value.
*2 When rated current is applied to the products, temperature rise caused by self-generated heat shall be limited to 40°C
max.
*3 Keep the temperature (ambient temperature plus self-generation of heat) under 125°C.
4. Testing Conditions
