Current-compensated chokes designed for a maximum voltage of 300VAC

Designed for a maximum voltage of 300VAC and offering inductance values of between 10mH and 100mH, Epcos' current-compensated chokes are now available from Digi-Key. At an operating temperature of 40C, the chokes can handle rated currents of between 0.7A and 2.3A. Both the plastic frame and the epoxy-resin coating meet UL94 V-0 requirements. In addition to their good common-mode suppression, the chokes feature good differential-mode suppression thanks to their relatively high stray inductance of about two percent. In many cases this means that no additional components for differential-mode suppression are required. The chokes are therefore particularly suitable for new designs of switch-mode power supplies with high-switching frequencies.
