This range of chokes enables horizontal mounting, thus reducing the

height of mounted circuit. Finest quality core materials allow the

highest electrical performance with minimum component volume.

Good design with easy assembly allows good cost/performance ra-

tio.

This type of choke is essential in the field of power electronics, e.g.

switching power supplies, chopper amplifiers, DC drives and stepper

motor controls.

DSF

Storage chokes are used as energy stores in switch mode

power supplies. Principle features:

- reduced magnetic reversal

- constant inductance at high alternating field modulation

and high DC magnetisation.

Environmental Ratings:

The

DSF chokes

can only be used with high frequency alternating

current or with HF-modulated direct current up to 1 MHz, under

consideration of their self heating (I

and

at f

) and of the ambi-

ent temperature (ϑa).
