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

) up to the range of their self-reso-
nance (∼f

SMD-version upon request.
Also available in open version (DLO1).
