EPCOS / TDK B82724J8 Power Line Chokes

EPCOS/TDK B82724J8 Power Line Chokes are current-compensated ring core double chokes for DC-link and power line applications. These chokes feature high resonance frequency due to a unique winding technique. The B82724J8 chokes offer significantly increased nominal inductance and current values at high-rated temperatures. These chokes are completely potted for local reduction of pollution degree and thermal stability. The B82724J8 chokes can suppress common-mode interferences and be used in switch-mode power applications, high-voltage applications, and frequency converters.
