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.

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 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

2	Inductance measured at 500 kHz, 0.1 Vrms using an Agilent/HP 4263B 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 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.
9	Electrical specifications at 25°C.
