Shielded Power Inductor – FA2769-AL
The FA2769-AL was developed for Enpirion for use in the
second stage LC filter for the output of their 6A DC‑DC
power modules EN5360D, EN5365Q and EN5366Q, and
for their 3A DC-DC power modules EN5330D, EN5335Q,
and EN5336Q.
This part is designed for applications requiring high current
handling capabilities and low DC resistance. Its compact
size makes it an excellent choice for use in notebook
computers, mobile phones, and other handheld products.

1. When ordering, please specify packaging code:
FA2769-ALC
C = 7″ machine-ready reel. EIA-481 embossed plastic
tape (750 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 (3000 per full reel). Factory order only, not
stocked.
2. Inductance tested at 500 kHz, 0.1 Vrms using an Agilent/HP 4284.
3. DCR is measured on a micro-ohmmeter at points indicated.
Packaging:
4. SRF measured using an Agilent/HP 8753ES network analyzer or
equivalent.
5. DC current at which the inductance drops 20% (typ) from its value without current.
6. Current that causes a 40°C temperature rise from 25°C ambient.
7. Ambient temperature range: –40°C to +85°C with Irms current
+85°C to +125°C with derated current
8. Storage temperature range: Component: –40°C to +125°C
Packaging: –40°C to +80°C
9. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
