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
- 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.

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
EIA-481 embossed plastic tape.
Parts per reel data
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" reel, machine-ready reel
EIA-481 embossed plastic tape. Factory order only, not stocked. Parts per reel data

Inductance measured at
500 kHz,
0.1 Vrms using an Agilent/HP 4263B LCR meter or equivalent. |

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 |

Storage temperature range: |
Component: –40°C to +125°C
Packaging: –55°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. |
