Electronic devices are often affected by electromagnetic interference, which degrades signal quality. Traditional filtering solutions have limited effectiveness and consume a lot of space. Our series of common-mode inductor products, using high-permeability magnetic cores and special winding techniques, have been applied by a certain communication equipment manufacturer in Vietnam. After application, the product passed the EMC test with a qualified rate from 75% to 98%, and the customer reported a significant reduction in the rework rate of the production line.
Core features of the product
- The Ring Common Mode Inductor adopts a ring-shaped core structure, providing a 360° uniform magnetic path.
- The UU Common Mode Inductor features a dual shielding design, effectively reducing leakage flux.
- The Vertical Plug-in Common Mode Inductor supports automated assembly, enhancing production efficiency.
- The Power Line Common Mode Choke can withstand a maximum current of up to 20A and has excellent temperature stability.
Cautionary Notes:
① Avoid mechanical stress on the core during installation
② The recommended operating environment temperature range is -40°C to +125°C
③ Avoid close placement with heat-generating components
④ Regularly check the soldering status of the pins
"Common Questions Answered"
Question: How to select the appropriate Common Mode Inductor?
Answer: The selection should be based on the interference frequency, impedance characteristics and rated current.
Question: How effective is the shielding of the UU Common Mode Inductor?
Answer: It uses a double-layer shielding cover, reducing magnetic field leakage by more than 60%.
