PFL4514 Series
Shielded Power Inductors

  • Only 1.4 mm high; requires only 16 mm2 of board space
  • Handles current up to 4.2 Amps
  • Magnetic shielding allows high-density mounting
  • For lower DCR and higher current in a slightly taller part, consider the PFL4517 series.
  • RoHS-compliant, halogen free. 260°C compatible. Matte tin over nickel over silver-platinum-glass frit terminations
  • 3 of each value and 3 of each PFL4517 are available in Coilcraft Designer's Kit C451

1 When ordering, please specify termination and packaging codes: e.g. PFL4514-223MEC
  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 (1000 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 (5000 parts per full reel).
2 Inductance tested at 100 kHz, 0.1 Vrms using an Agilent/HP 4263B LCR meter.
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 25°C that causes the specified inductance drop from its value without current.
Temperature derating curves.
6 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.
7 Ambient temperature range: −40°C to +85°C with (40°C rise) Irms Derating curves
8 Storage temperature range: Component: −40°C to +125°C
Tape and reel packaging: −40°C to +80°C
9 Maximum part temperature: +125°C (Ambient + temperature rise)
10 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.
11 Electrical specifications at 25°C.
Refer to Soldering Coilcraft Components before soldering.
PCB washing: Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info.
