EPL3314 Series
Shielded Power Inductors

The EPL3314 series is not available for new designs. For improved performance and higher inductance values, we recommend the XFL3012 and LPS3314 Series as an alternative.

For additional recommendations to optimize your design, please use our Power Inductor Finder Tools.


  • Ultra-small shielded power inductor – only 1.45 mm high, 3.2 × 3.3 mm footprint
  • Handles current up to 2.3 Amps
  • Magnetic shielding allows high-density mounting
  • Soft saturation, perfect for VRM/VRD applications
  • RoHS-compliant, halogen free. 260°C compatible. Tin-silver-copper (96.5/3/0.5) over tin over nickel over silver-platinum terminations

1 When ordering, please specify termination and packaging codes: e.g. epl3314-333MLC
Termination: L = Tin-silver-copper (96.5/3/0.5) over tin over nickel over silver-platinum
Special order, added cost: S = 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
In tape, but not machine-ready. To have a leader and trailer added ($25 charge), use code letter C instead.
D = 13" machine-ready reel
EIA-481 embossed plastic tape. Factory order only, not stocked (7500 parts per full reel).
2 Inductance tested at 1 MHz, 0.1 Vrms, 0 Adc.
3 DCR measured at 25°C on a micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator.
4 SRF measured using an Agilent/HP 4395A network analyzer or equivalent.
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.
