SMT Power Inductors - MLC Series

Document 327-1

Document 327-1 Revised 11/11/05

The MLC series of flat wire power inductors offers ex-

tremely low DC resistance and very high saturation current

ratings (up to 37 Amps). Its compact size and magnetic

shielding make it suitable for use in high-density boards.

These inductors are ideal for power supply applications

where high current handling is essential. They are perfect

for use in VRD/VRM controllers.

Inductance is unaffected by ambient temperature up to

+135°C. The materials used in the unique design elimi-

nate all thermal aging issues. Custom inductance values

are also possible.

Coilcraft Designer’s Kit C187 contains samples of all

values shown. To order, contact Coilcraft or purchase on-

line at http://order.coilcraft.com.

1. When ordering, please specify packaging code:

MLC1550-452MXC

Packaging: C =7″ machine-ready reel. EIA-481 embossed plastic

tape.

B= Less than full reel. In tape, but not machine ready.

To have a leader and trailer added ($25 charge),

use code letter C instead.

D=13″ machine-ready reel. EIA-481 embossed plastic

tape.

2. Inductance measured at 500 kHz, 0.1 Vrms, 0 Adc using a Coilcraft

SMD-A fixture in an Agilent/HP 4284A LCR meter.

3. DC current at which the inductance drops 20% (typ) from its value

without current.

4. Average current for a 40°C (max) rise above 25°C ambient.

5. Operating temperature range −40°C to +135°C.

6. Electrical specifications at 25°C.
