- (1) Open Circuit Inductance Test Parameters: 100KHz, 0.25Vrms, 0.0Adc. 

- (2) RMS current for an approximate ∆T of 40°C without core loss. It is recommended that the temperature of the part not exceed 125°C. 

   - (4) DCR limits @ 20°C. 

   - 5) Applied Volt-Time product (V-uS) across the inductor at 100kHz necessary to generate a core loss equal to 10% of the total losses for 40°C temperature rise. 

- (3) SD10,12,18,25 Peak current for approximate 30% roll off at 20°C. SD14 Peak current for approximate 20% roll off at 20°C.
