Bourns recently unveiled two new high current common mode choke models, the SRF1206A-501Y and SRF1206A-172Y. Engineered to provide more impedance and current options for designers, these models are an extension of Bourns AEC-Q200 compliant, automotive grade SRF1206A Series.
These chokes deliver high impedance over a broad frequency range to provide an effective EMI suppression and noise filtering solution for in-vehicle switch-mode power supplies as well as other automotive, consumer and industrial systems.
These two new common mode choke models feature a monolithic ferrite core with a closed-loop magnetic path, offering excellent magnetic shielding performance. They are constructed with a sector-wound configuration that helps enhance dielectric strength between windings. The impedance range of these two models extends from 500 to 1700 ohms (Ω), with current ratings up to 10A and an operating temperature range from -40 to +125 °C.
