EPCOS Product Brief 2014 High-Current Chokes Current-Compensated Common-Mode Chokes New high-current common-mode Derating Curve chokes featuring: ■ Ambient temperatures based on 70°C part rating ■ Glueless design ■ Derating curve based on 70°C ■ High voltages 600 V/1000 V part rating ■ UL class F (155°C) ■ Operating current of chokes to Compact electrical and electronic follow curve equipment primarily generates common-mode interference. In ■ AC voltages rated at 50/60 Hz order to be able to meet the safety requirements (keeping within the leakage current limits), chokes with a high asymmetrically effective inductance must be used. Currentcompensated chokes with a closed core topology are especially suitable for this purpose. The problem of core material saturation due to the useful current is solved in these designs by winding two coils with equal number of turns on the core. These coils are connected in such a way that the magnetic flux induced by the upper coil is compensated by the lower coil. www.epcos.com Ir 1.4 Iop 1.2 Tr = 70°C 1.0 0.8 0.6 0.4 0.2 0 0 20 40 60 80 100 120 140 °C Magnetic Flux Selection Guide 1 0.1 Current [A] B82725S B82726E/S B82727E B82746S B82747E B82767S Magnetic flux induced in core by operating current Operating Current 10 100 100 Ferrite core 10 Line Magnetic flux induced in core by disturbing interference current Disturbing interference source Common-mode interference current distributing asymmetrical interference High Current Chokes Low Current Chokes Inductance [mH] Current flow through windings 1 B82791G/H B82720A/K B82721A/J/K B82722A/J B82723A/J B82724A/J B82724B B82725A/J 0.1 High-Current Chokes [A] [mH] Lr L-tol.
