Operating temperature range -55°C to 125°C. 2. Isat for Inductance drop 30% from its value without current. 3. Irms for a 40°C temperature rise from 25°C ambient. 4. The part temperature (ambient + temp rise) should not exceed 125°C under worst case operating conditions. Circuit design 125°C under worst case operating conditions. Component placement, PCB trace size and thickness, airflow and other cooling provisions all affect the part temperature. Part temperature should be verified in the end application. 5. Absolute maximum voltage 30V DC. (Based on test method, it may not the sameunder different application, it is recommended to verify first.) ## **BMRB00060624 Series Specification** ~~LE~~ 8 **BMRB00060624 Series 8.1 Construction** **==> picture [68 x 80] intentionally omitted <==** **----- Start of picture text -----**
