TDK Corporation presents a new series of current-compensated EPCOS double-ring core chokes for the suppression of common-mode interferences.

Aggregate earth leakage currents can often cause RCDs (residual current devices) to trip at their threshold. As a result, RCDs are either not usable or only with substantial additional outlay.

TDK Corporation (TSE:6762) has extended its range of EPCOS power line chokes to include six new types. The new components are available in three different core shapes with different rated currents and inductance values, delivering great design flexibility.

TDK Corporation announces that it has reengineered and improved the EPCOS LeaXield™ active leakage current filter, a unique solution that is able to minimize earth leakage currents in converter-based drive systems.

The individual components in variable-speed drives cause earth leakage currents that cumulatively result in the tripping of the RCD. By using the upgraded EPCOS LeaXield™ active leakage current filter, these earth leakage currents be drastically reduced.

TDK Corporation presents a new series of EPCOS current-compensated ring core power line double chokes. The RoHS-compatible B82724J8*N040 series features a high rated voltage of 800 V DC or 250 V AC in continuous operation and was developed specifically for use as DC link chokes in frequency converters.

TDK Corporation is expanding the B84243* series of EPCOS 3-line EMC filters to include 10 new types for currents of up to 280 A. All 18 types in the series are designed for a rated voltage of 530 V AC.
