1. When ordering, please specify termination and packaging codes:
MVR1278C-232M
LC
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.
Core material MVRxxxT: Ferrite; MVRxxxxC: Powdered iron
Core and winding loss See www.coilcraft.com/coreloss
Terminations RoHS compliant tin-silver over copper. Other
terminations available at additional cost.

PCB washing Only pure water or alcohol recommended
The MVR series provides greater current handling ca-
pability 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 converters, battery-powered devices and high cur-
rent power supplies. Their flat wire construction en-
sures 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 satu-
ration 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.
