PFL2510 Series

Shielded Power Inductors

PFL2510 ultra-small molded power inductors offer the perfect combination of size, performance and price. PFL inductors feature soft saturation for high peak currents and magnetic shielding for high-density packaging.

Only 1 mm high; requires only 6.4 mm² of board space
Tiny, cost-effective molded power inductors
Soft saturation for peak current handling
Magnetically shielded
No thermal aging

Notes

When ordering, please specify termination and packaging codes: e.g. PFL2510-472MEC
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.
DCR measured at 25°C using a micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator.
SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD-D test fixture.
Isat: DC current at 25°C that causes the specified inductance drop from its value without current. Temperature derating curves.
Irms: Current that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Temperature derating curves.

Termination:

E = Halogen free component. RoHS-compliant matte tin over nickel over silver-platinum-glass frit terminations.
Q = RoHS tin-silver-copper (95.5/4/0.5). (Special order, added cost)
P = non-RoHS tin-lead (63/37). (Special order, added cost)

Packaging:

C = 7″ machine-ready reel. EIA-481 embossed plastic tape (2000 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
D = 13″ machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked (7500 parts per full reel).
B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to C.
