Sendust core inductance introduction 

1 sendust core inductor standard components are: AL5.4%; Si9.6%; the other is iron.

More than 2 sendust core inductor Curie temperature of 410 degrees, temperature range of -50~+200 degrees

3 sendust core inductor current superposition of good performance, low loss, negative temperature coefficient

4 sendust core inductor of initial permeability I has the following file: 26 Mu Mu E; e 60 mu 75 mu; E; e 90 e 125 mu.

Inductance coefficient AL

The inductance is self inductance per turn coil core, i.e.

In the formula L for self inductance magnetic core coil (unit: H), N is the number of turns of the coil.

Saturation induction Bs 5 sendust core inductor value is: 800-1000mT.

The saturation magnetic induction of Bs is in the operating temperature (25 degrees or 100 degrees Celsius), with the magnetic intensity of magnetic material is large enough, the magnetization curve close to the horizontal line (see below), no longer with the magnetic field strength is obviously increased B values, called saturation induction Bs.
