HCT

High Current Toroidal Inductors

This information is

intended to be used in

assisting the designer in

part selection. Each

application may contain

other variables which

must be considered in

part selection, such as

temperature effects,

waveform distortion, etc.

API Delevan

Sales/Engineering is

available to provide

information as needed to

fit each application.

Data is representative of

a DC current with less

than 1% ripple and an

AC waveform less than:

50 gauss on the

HCT-37X, 25 gauss on

the HCT-44X, 15 gauss

on the HCT-50X and 10

gauss on the

HCT-68X.The effect of

AC or ripple flux can be

significant in many DC

inductor applications.

When significantly

greater AC flux density is

present, it becomes

necessary to consider its

effect on both core loss

and permeability

(inductance).

All data points, on the

above graphs, that

exceed the rated DC

current specified for a

55°C rise from a 25°C

ambient are for design

reference only and are

not intended to imply

continuous use at those

DC current levels.
