【GCMH Series】Common Mode Choke-Highly effective noise suppression, an ideal choice for enhancing power circuit designs-Low DCR

Common Mode Coil is a filter that reduces common-mode noise that becomes problematic in differential transmission lines, power lines, and audio lines. (Example: Universal Transport Interface Power Supply: Thunderbolt-3 / USB3.1&4.0 / HDMI 1.3& 2.1 / Type C / MIPI C-PHY...) etc. / Wireless charging transmission WPC / WiFi 6 / Automotive: CAN/CAN-FD/100Base-T1/1000Base-T1/SerDes/A2B®, etc.)
The characteristics of common mode chokes have no effect on the signal (high cutoff frequency) and are best suited for eliminating common mode noise from MHz to hundreds of MHz.

GOTREND  GCMH Series common mode choke coils (Common Mode Filter) are different from the traditional plug-in toroidal coil structure. They are wound with high magnetic permeability magnetic materials and flat copper wires. They can still have extremely low DCR under high inductance. Improve the saturation current and temperature rise current capability to meet the needs of the application side in the design of high-power lines.

GCMH Series is designed with the concept of power transformers, using high-strength Bakelite skeleton to carry. This not only enhances the overall structural strength but also promotes higher plug-in operation efficiency in application end production.
In addition, with the production of automatic flat copper wire winding equipment, effectively overcomes the problems of wire damage and short circuit caused by manual threading of traditional toroidal coils in the past.

High-quality electrical performance, high-strength product structure, and stable production quality are absolutely sufficient to meet the application requirements of automotive applications and high-end electronic products.
