SMD Common Mode Chokes / Filters :

We offer SMD Common Mode Chokes and Filters with inductance values from 0.245nH to 100mH, and DC current ratings form to 35mA to 1kA.

Below are examples of some of manufacturers’ product ranges:

Murata offers their DLW31S range of high-performance wound type SMD Chip Common Mode Choke Coils. With high common mode impedance, they are suitable for noise suppression through a wide frequency range.

• Suitable for noise suppression in car area networks like CAN bus
• -40 to 125°C Operating temperature range

Also used in applications like Industrial, Communications & Networking, and Safety.

Coilcraft offers their 0805USB series common mode chokes. This Series was designed for common mode noise suppression in high-speed differential signal lines (USB2.0, IEEE1394, and LVDS) and provides up to 3.4GHz differential mode 3dB cutoff frequency. They provide up to 2kOhm common mode peak impedance and more than 30dB common mode noise attenuation.

Bourns SRF3216 Series of common mode chip inductors feature high impedance values, current ratings to 400mA, and are RoHS compliant.

Applications include noise suppression, personal computers, and display panels.

Abracon’s ACMP-5025 Series of power common mode chokes are commercial grade and PPAP ready. They have excellent impedance characteristics, and rated currents up to 6.5A. They have extremely low DCR.

Applications include DC power line common mode noise suppression, switch mode power supplies and regulators, variable frequency drives, and AC/DC power rectifiers.
