TDK-EPC has released a new sample kit of EPCOS current-compensated ring core power chokes designed for a voltage of 250 V AC with current capabilities of between 0.4 and 6.0 A. The EMC components have inductance between 0.2 and 39 mH. The power chokes of the series B82721 are designed for suppression of common-mode interference in compact switch-mode power supplies as well as converters of all types.
The new series is capable of suppressing symmetrical interference, thanks to their stray inductance of about 1 percent of the rated inductance. The sample kit contains a selection of available types in horizontal with dimension of 17.9 x 17.3 x 12.6 mm3 (L x W x H) and vertical versions with dimension of 18.2 x 13.2 x 20.3 mm3 (LxWxH). The new series are in compliance with UL, VDE and RoHS.
