VRM/ VRD Power Inductors – MVR

MVR1251T only

The MVR series provides greater current handling

capability than any other power inductor its size. While

requiring only one square centimeter of board space, this

inductor can handle up to 36 Amps of current.

These shielded inductors were developed for multi-phase

voltage regulators and are ideal for use in DC-DC con-

verters, battery-powered devices and high current power

supplies. Their flat wire construction ensures very low

DC resistance and offers an excellent performance-to-

height ratio. The materials used in these parts eliminate

all thermal aging issues.

The MVR12xxT is a high efficiency part that features very

low core loss. The MVR12xxC provides soft saturation

and is unaffected by part temperature up to 125°C.

Refer to the comparison curves for L vs Current and ESR

vs Frequency for performance differences.

1. When ordering, please specify

termination

and

packaging

codes:

MVR1278C-232MLC

Termination: L

= RoHS compliant tin-silver over copper.

Special order: T

= RoHS tin-silver-copper

(95.5/4/0.5) or

= non-RoHS tin-lead (63/37).

Packaging: C

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

tape.

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

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

use code letter C instead.

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

tape. Factory order only, not stocked.

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

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

3. SRF measured on an Agilent/HP 8753ES.

4. DC current at which the inductance drops 30% (typ) for MVR12xxC

and 20% (typ) for MVR12xxT from its value without current.

5. Current that causes a 40°C temperature rise from 25°C ambient.

6. Electrical specifications at 25°C.

Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
