Horizontal common-mode choke

Schurter has expanded its DKFS range of SMD chokes with a horizontal version. With it, the use of high-performance, compact chokes is possible in low-profile assemblies.

Modern electronic circuits require components with the highest performance in ever smaller profiles - the horizontal DKFS chokes are suited for this purpose. Compared to vertical models, they have higher inductance with the same rated current. Thanks to SMD leads, they can be assembled using the same re-flow soldering process as other components. Possible application areas include switch-mode power supplies, DC and stepping motor drives and frequency converters.

With a rated voltage of 250 VAC, the common-mode chokes are designed for temperatures of -40 to +125°C. They will also continue to be available in vertical models as well as in the horizontal design. The DKFS series meets the requirements of IEC/EN60938 and is UL1283 approved.

Other features include: rated current 400 mA to 4 A; inductivity 0.7 to 39 mH; SMD leads; and attenuation of common-mode interference.
