Epcos has added the B82732F and B82733F series to its range of current-compensated chokes. The new series feature one of the best inductance/rated current ratios worldwide, said the company. High leakage inductance makes the chokes suitable for interference suppression in switch-mode power supplies, lamp ballasts and a host of applications in industrial electronics. Due to their coated frame cores and multichamber coil formers, a high natural resonant frequency is obtained.

Current-compensated chokes of series B82732F are designed for currents from 0.5A to 1.7A with inductances from 10mH to 100mH. Inherent resistance ranges from 260 m? to 2840 millohms. Series B82733F covers the current range from 0.75A to 2.9A, with inherent resistances from 130 m? to 1,700 m?. Inductance ratings are identical with those of series B82732F. The chokes are designed for an operating voltage of 250Vac.

The footprint measures 24-by-14mm with an insertion height of 14mm. Approval to EN 60938-2 and UL 1283 is pending.
