LPH8045 Series

3-Winding Coupled Inductors/Transformers

Our versatile LPH8045 Series shielded coupled inductors include three 1:1 windings for a variety of configurations as transformers, or as a SEPIC inductor. Magnetic shielding allows high density mounting.

Three 1 : 1 windings can be wired in a variety of ways:
As a 1 : 1, 2 : 1 or 1 : 2 transformer;
as a 1 : 1 transformer with an aux winding;
as a gate drive transformer;
as a SEPIC inductor; etc.
Low DCR
Excellent current handling
Magnetically shielded

メモ

When ordering, please specify packaging code: e.g. LPH8045-223MRC
Inductance is for each winding, measured at 100 kHz, 0.1 Vrms, 0 Adc
DCR is for each winding, measured at 25°C on a micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator.
SRF measured using an Agilent/HP 8753ES or equivalent.
Isat: DC current at which the inductance drops the specified amount from its value without current. Details
Irms: Current through one winding that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.

終端処理:

RoHS compliant matte tin over nickel over silver. Other terminations available at additional cost.

パッケージ:

C = 7″ machine-ready reel. EIA-481 embossed plastic tape (250 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
D = 13″ machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked (1000 parts per full reel).
B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to C.
