SER2211 Series

Shielded Power Inductors

SER2211 Series high-current, high-inductance power inductors feature a flat-wire construction, resulting in exceptionally low DC resistance. They come in a wide range of sizes and inductance values for POL, VRM, VRD, and other high power applications.

Rugged flat wire construction
Exceptionally low DC resistance
Ferrite core for flat L vs. I characteristics
Magnetically shielded to minimize EMI

Notes

When ordering, please specify termination code: e.g. SER2211-473MED
Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4284A or equivalent.
DCR measured at 25°C on a micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator.
SRF measured using an Agilent/HP 4391A impedance analyzer and an Agilent/HP 16193A test fixture. Details
Isat: DC current at 25°C that causes the specified inductance drop from its value without current. Temperature derating curves.
Irms: Current that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Temperature derating curves. When Irms is greater than Isat,Isat is the more critical specification and Irms is shown in gray type. See temperature rise vs Current.

Termination:

E = RoHS compliant matte-tin over nickel over phos bronze.
Q = RoHS tin-silver-copper over copper (95.5/4/0.5). (Special order)
P = non-RoHS tin-lead (63/37). (Special order)

Packaging:

D = 13″ machine-ready reel. EIA-481 embossed plastic tape (200 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
