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