Coilcraft's new Cx family of EMI chokes

New EMI Chokes Target Consumer Electronics and Industrial Apps

Coilcraft’s new family of EMI chokes with current ratings of up to 10 A can withstand a maximum reflow temperature of 260°C.

Coilcraft’s new Cx family of surface-mount common-mode chokes includes 16 sizes/configurations for a broad range of power-line circuits. They suppress high-frequency common-mode noise up to 100 MHz and offer greater than 40 dB common-mode attenuation, suiting them for use in consumer electronics and industrial applications, according to the company.

The company says all Cx family EMI chokes feature a low-profile, toroidal construction in a surface-mount, magnetically shielded package with footprints as small as 13 x 13 mm. They're available with current ratings of up to 10 A (Irms) and provide 1000/1500 Vrms isolation (hipot) between windings. The chokes feature RoHS-compliant tin-silver-copper over tin over nickel over phosphor bronze terminations and can withstand a maximum reflow temperature of 260°C.
