High Power Density, High Efficiency, Shielded Inductors
Description
• 125°C maximum total operating temperature
• Four sizes of shielded drum core inductors
• Inductance range from 0.33µH to 1000µH
• Current range up to 56 amps peak
(1) Open Circuit Inductance Test Parameters: 100kHz, 0.25V rms , 0.0Adc.
(2) RMS current for an approximate ∆T of 40°C without core loss. It is recommended that the
(3) Peak current for approximate 30% roll off at 20°C.
(4) DCR limits @ 20°C.
(5) Applied Volt-Time product (V-µS) across the inductor. This value represent the applied V-µS
