DR Series

High Power Density,

High Efficiency, Shielded Inductors

Description

• Four sizes of shielded drum core inductors

• Inductance range from 0.33uH to 1000uH

• Current range up to 56 Amps peak

• Frequency range up to 3MHz

• Magnetic shielding

• Secure mounting

Applications

• Computer, DVD players, and portable power devices

• LCD panels

• DC-DC converters

• Buck, boost, forward, and resonant converters

• Noise filtering and filter chokes

Environmental Data

• Storage temperature range: -40C to +125C

• Operating ambient temperature range: -40C to +85C

(range is application specific). The internal “hot-spot”

temperature defines the maximum allowable currents,

which are limited to 130C, including ambient.

• Infrared reflow temperature: +240C for 30 seconds max.

(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.

(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 at 100KHz necessary to generate a core loss equal to 10% of the

total losses for 40°C temperature rise.
