Riverside, California – December 9, 2020 – Bourns Magnetics Product Line is introducing the AEC-Q200 Compliant Model SRF1206A and SRF9045A High Current Common Mode Choke Series. These chokes offer compact size and high impedance over a broad frequency range to suppress Electromagnetic Interference (EMI) either coming into or leaving the system.

The windings of both the Model SRF1206A and SRF9045A series common mode chokes have a sector-wound configuration. In addition to the normal common mode impedance that the design isintended to achieve, this construction also features increased differential mode impedance at high frequency range. The SRF1206A and SRF9045A series provide not only common mode filtering but also differential mode filtering in a single choke configuration. The operating temperature rangesfrom -40 to +125 °C.

These high current common mode chokes are ideal for use in DC/DC converters,switch-mode power supplies and power line noise suppression in consumer, industrial and other electronics.

Product Characteristics: Model/ Product Size/ Inductance /Typical CM Impedance /Current /

SRF9045A 9 x 7 x 4.5 mm 7.5 µH 700 Ω @ 100 MHz 5 A

SRF1206A 12 x 11 x 6 mm 9 & 12.5 µH 700 & 1000 Ω @ 100 MHz 6 & 8 A
