Munich, Germany 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. High leakage inductance makes the chokes ideal for interference suppression in switch-mode power supplies, lamp ballasts and a host of applications in industrial electronics. Thanks 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 0.5 to 1.7 A with inductances from 10 to 100 mH. Inherent resistance ranges from 260 to 2840 mOhm. Series B82733F covers the current range from 0.75 to 2.9 A with inherent resistances from 130 to 1700 mOhm. Inductance ratings are identical with those of series B82732F. The chokes are designed for an operating voltage of 250 VAC. The footprint measures 24 x 14 mm with an insertion height of 14 mm. Approval to EN 60938-2 and UL 1283 is pending.
