SMPI Tai-Tech Advanced Electronics (H.K.) Co., Ltd., SMPI Datasheet - Page 2

• Manufacturer Part Number: SMPI
• Description: Ultra High Current Power Inductors Smpi Series On-board Type Hi-current Power Inductors
• Manufacturer: Tai-Tech Advanced Electronics (H.K.) Co., Ltd.

●
Note:
1. Test frequency : 100KHz / 0.25Vdc
2. Testing Instrument : L: HP4284A, CH11025, CH3302, CH1320, CH1320S LCR METER / Rdc:CH16502,Agilent33420A MICRO OHMMETER.
3. Heat Rated Current (Irms) will cause the coil temperature rise approximately △T=40℃ without core loss.
4. Saturation Current (Isat) will cause L0 to drop approximately 20%
5. The part temperature (ambient + temp rise) should not exceed 125℃ under worst case operating conditions. Circuit design, component, PCB trace size and
thickness, airflow and other cooling provisions all affect the part temperature. Part temperature should be verified in the end application.
