Chokes in vertical version enable a very space economising, compact structure on the printed circuit board. All choke types comply with the guidelines of EN 60938-2 and also bear the test label. In combination with suitable capacitors, high quality interference suppression filters against parasite interference influences are achieved.

Main application fields are: generai purpose filtering of parasite disturbance factors, above ali with asymmetric interferences e.g. in frequency converters, switch mode power supplies, automotive electronics, etc. Optimum adaptation of core materials and technical design guarantee the best possible compliance with the world-wide high requirements with the smallest volume. The simple construction enables high performance parameters with the smallest heat development and an optimum price-performance ratio. Four closed housings are complemented by one version in open structure.
