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.  
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.  
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.  
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 (IN and DI at f0) and of the ambi-  
ent temperature (ϑa).
