All types of chokes correspond to the international specifications for

radio interference chokes (EN 138100).

Thisrangeof chokesenableshorizontalmounting, thusreducingtheheight

of the mounted circuit. Finest quality core materials allow the highest

electrical performance with minimum component volume. Good design

with easy assembly allows good cost/performance ratios.

Thistypeof chokeisessentialinthefieldof powerelectronics, e.g. switching

powersupplies, chopperamplifiers, DCdrivesandsteppermotorcontrols.

DLF Linear chokes are mainly used as smoothing or RFI suppres-

sion circuits.

Environmental Ratings:

The DLF chokes can only be used with direct current or with low

frequency alternating current (max. 400 Hz) and up to max I_N• 1.1.

They operate only as attenuation devices for HF-interference with

reduced amplitude (DI << I_N) up to the range of their self-reso-

nance ( f_Res).

SMD-version upon request.
