EPL3314 Series
Shielded Power Inductors

  • 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.
