Common Mode Chokes

Laird Common Mode Chokes are designed for power, low-frequency, and high-frequency signal lines. The chokes can withstand high DC currents without degrading filtering performance and remain stable under load bias. The compact chokes feature low DCR and offer excellent impedance versus frequency. Laird Common Mode Chokes can be used for USB, HDMI, 1394, DVI, S-ATA, and LVDS signal line applications.
