All types of chokes correspond to the international specifications

for radio interference chokes (EN 138100).

This range of chokes enables vertical mounting, thus reducing the

area of the PC board used. 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.

DLH

DLNP

Linear chokes are mainly used as smoothing or RFI sup-

pression circuits.

Environmental Rating:

The

DLH and DLNP chokes

can only be used with direct current or

with low frequency alternating current (max. 400 Hz) and up to max.

They operate only as attenuation devices for HF-interference

with reduced amplitute (DI << I
