Wire Wound Chip Common Mode Choke Coil—SDCW2012CH Series
Overview

The common mode impedance of wire wound chip common mode choke SDCW2012CH ranges in 67Ω~120Ω, with packaging size 2.0mm*1.2mm*0.9mm. The product adopts an open magnetic circuit structure with a ferrite skeleton, parallel winding enamelled copper wire for the conductor and a magnetic core coated with resin at backside. The choke has good suppression for noise in the high-speed different signal lines, such as HDMI, DVI high-speed differential signal interface, USB interface of portable audio/video devices and tablets.

Background

SDCW2012CH series employ UV glue coating process which provides strong protection on the back and flank of the products. Compared with conventional plate-structured common mode products, not only the reduced height, but also no potential breakage caused by excessive stress on the plate, and better machining stability at high temperature.
