LD Series

Metalized Drum Core

Power Inductor

Description

• Metalized drum core design utilizes board space

• Current Range from 4.46 to 0.52 Amps

• Inductance range from 1.0 uH to 470uH

• RoHS compliant (-R option)

Applications

• Buck or Boost inductor

• Noise filtering and output filter chokes

• Computers

Notes:

3) Peak current for an approximate 10% rolloff at 20°C

4) DCR limits @ 20°C

1) Open Circuit Inductance Test Parameters: 100kHz, 0.25Vrms, 0.0Adc +/-20%

except for LD1-330 to LD1-680 and LD2-470 to LD2-471 which is +/-10%

2) RMS current for for an approximate T of 40°C. It is recommended that the

temperature of the part not exceed 125°C
