MVR Series
VRM/VRD Power Inductors
- Ideal for low-voltage, high-current DC-DC converters and VRM/VRD controllers
- Best current handling of any inductor its size
- Low profile with excellent performance-to-height ratio.
- Low core loss and soft saturation versions
- MVR1251T are rated AEC-200 Grade 1 (-40°C to +125°C)
- For soft saturation version, inductance is unaffected by part temperature up to +125°C, with no thermal aging issues.
- COTS Plus tin-silver-copper and tin-lead terminations available
- RoHS compliant. 260°C compatible. Tin-silver over copper terminations.

| 1 | When ordering, please specify termination and packaging codes: e.g. MVR1278C-232MLC | |
| Termination: |
L =
RoHS compliant tin-silver (96.5/3.5) over copper. Special order, added cost: T = RoHS tin-silver-copper (95.5/4/0.5) or S = non-RoHS tin-lead (63/37). |
|
|
Packaging:
|
C = 7" reel, machine-ready reel
B = Less than full reel
D = 13" reel, machine-ready reel |
|
| 2 | Inductance measured at 500 kHz, 0.1 Vrms using an Agilent/HP 4284A LCR meter or equivalent. | |
| 3 | SRF measured on an Agilent/HP 8753ES | |
| 4 | Isat: DC current at which inductance drops 20% (typ) from its value without current. Details | |
| 5 | Irms: Current that causes the specified temperature rise from 25°C ambient. Details | |
| 6 | Ambient temperature range: |
–40°C to +85°C with Irms current. +85°C to +125°C with derated current Derating curve |
| 7 | Storage temperature range: | Component: –40°C to +125°C T&R packaging: –40°C to +80°C |
| 8 | Resistance to soldering heat: Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between. | |
| 9 | Electrical specifications at 25°C. | |
| Refer to Soldering Coilcraft Components before soldering. | ||
