Sendust

 

    Distributed air gap toroid cores made from silicon iron alloy powders. Material permeability's range from 26µi to 125µi with standard core sizes from 6.35mm to 58.0mm. Cores are coated with an epoxy coating which provides a tough outer surface with a minimum breakdown voltage of 500Vac. Sendust cores are colour coded in black.

 

    Magnetic Properties

    High saturation flux density

    Good dc bias

    Low core losses

    Low cost

Applications

Switching regulator inductors

In-line noise filters

Power Factor Correction (PFC) inductors

Pulse and Fly-back transformers
