PFL2510 Series
Shielded Power Inductors

Only 1 mm high; requires only 6.4 mm² of board space
Handles current up to 4100 mAmps
Magnetic shielding allows high-density mounting
For higher current capability, consider the PFL2512 series
RoHS-compliant, halogen free. 260°C compatible. Matte tin over nickel over silver-platinum-glass frit terminations
5 of each value and 5 of each PFL2512 are available in Coilcraft Designer's Kit C444

1	When ordering, please specify termination and packaging codes: e.g. PFL2510-472MEC
	Termination:	E = Halogen free component. RoHS-compliant matte tin over nickel over silver-platinum-glass frit terminations. Special order, added cost: Q = RoHS tin-silver-copper (95.5/4/0.5) or P = non-RoHS tin-lead (63/37).
	Packaging:	C = 7" machine-ready reel EIA-481 embossed plastic tape (2000 parts per full reel). B = Less than full reel On reel but not machine-ready. To have a leader and trailer added ($25 charge), use code letter C instead. D = 13" reel, machine-ready EIA-481 embossed plastic tape. Factory order only, not stocked (7500 parts per full reel).

2	Inductance tested at 7.9 MHz, 0.1 Vrms using a Coilcraft SMD-A test fixture with an Agilent/HP 4286 impedance analyzer and Coilcraft provided correlation pieces.
3	DCR measured at 25°C using a micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator.
4	SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD-D test fixture.
5	Isat: DC current at which the inductance drops the specified amount from its value without current. Details
6	Irms: Current that causes specified temperature rise from 25°C ambient. Details
7	Ambient temperature range:	–40°C to +85°C with Irms current. +85°C to +125°C with derated current. Derating curve
8	Storage temperature range:	Component: –40°C to +125°C Tape and reel packaging: –40°C to +80°C
9	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.
10	Electrical specifications at 25°C.
Refer to Soldering Coilcraft Components before soldering.
PCB washing: Tested with pure water or alcohol only. Other solvents.
