1.
Introduction
Sendust cores are made by highly compacting
insulated alloy powder. The base material
is iron-silicon-aluminum alloy,known as Sendust.
These material cores offer various excellent
electro-magnetic properties, such as high
saturation flux density, low losses, high
resistivity, and stable permeability under
high DC bias conditions. Dongbu
Sendust cores are suitable for high frequency
power chokes and filters, especially in
switching mode power supplies (SMPS).

2. Availability
Dongbu Sendust cores are available in a variety
of physical sizes and three permeabilities
(60, 90,125). Epoxy coated toroidal cores
are typically supplied to the customers.
More detailed informations are refered to
the technical data on core properties and
dimensions in the following pages.
3. Advantages
- Core losses significantly lower than powdered
iron cores.
- Good DC Bias characteristics
- Cost between powdered iron and MPP
4. Major Applications
- Switching regulator inductors
- In-line Noise filters
- Pulse transformers, Fly-back transformers,
