Electrical specifications at 25ºC. 2. Tested at 100kHz. 3. Operating temperature range: -40ºC to +130ºC. Operating temperature is a combination of ambient temperature plus temperature rise. 4. Meets UL 94V-0. 5. Specifications shown are for an inductor with a 55ºC temperature rise. The core loss is 10% of the copper loss when operating at 500kHz. 6. Please remember it is much easier to remove heat from a copper-loss dominated design than from a core-loss dominated design.
