Our Surface Mount Common Mode Chokes are engineered to effectively suppress electromagnetic interference (EMI) in compact electronic systems. Designed for modern high-speed and high-density PCBs, these components provide reliable noise attenuation on signal and power lines while maintaining excellent electrical performance.
Compared with traditional through-hole solutions, SMD Common Mode Chokes enable automated assembly, reduced footprint, and improved consistency in mass production.
A Common Mode Choke is a passive magnetic component that blocks common-mode noise while allowing differential signals to pass with minimal attenuation. In surface mount form, it is optimized for space-constrained designs where EMI compliance and signal integrity are critical.
Unlike a Differential Mode Choke, which targets noise between signal lines, common mode chokes focus on suppressing noise that appears simultaneously on multiple conductors—making them essential for EMI control in digital and power electronics.
Effective EMI Suppression
Attenuates common-mode noise over a wide frequency range to help systems meet EMC standards.
Surface Mount Design
Optimized for reflow soldering and automated PCB assembly.
Compact & Lightweight
Ideal for miniaturized electronics with strict space limitations.
Low DC Resistance (DCR)
Minimizes signal loss and power dissipation.
Stable Electrical Performance
Consistent inductance under operating current and temperature variations.
Wide Selection Available
Multiple sizes, impedance values, and current ratings for different applications.
Surface mount common mode chokes are widely used in:
Switching power supplies and DC-DC converters
USB, HDMI, Ethernet, and communication interfaces
Industrial control systems
Consumer electronics and smart devices
Automotive electronics
Power entry modules and signal lines
They are often used alongside Power Line Filters and EMI Filter solutions to build a complete noise suppression network.
Our SMD common mode chokes are compatible with modern PCB layouts and can be easily integrated with other magnetic components such as Ferrite Bead Inductors to achieve enhanced EMI performance without increasing board complexity.
For higher current or line-level noise suppression, designers may also consider Power Line Common Mode Choke solutions in combination with surface mount devices.
