T25×10×15 Through Hole Ferrite Core Common Mode Inductor EMI Filter Coil for Power Supply

The T25×10×15 Through Hole Toroidal Common Mode Inductor is designed for EMI noise suppression and electromagnetic interference filtering in power supply systems and electronic equipment. Featuring a ferrite magnetic core and toroidal winding structure, this common mode choke helps reduce common-mode noise on power lines, supporting improved electromagnetic compatibility (EMC) and more stable operation of electronic devices.

For manufacturers facing electromagnetic interference, unstable signal performance, or EMC compliance challenges, this ferrite ring EMI filter coil offers a practical solution for power supply filtering and noise control. Its compact toroidal design supports efficient PCB integration, making it suitable for a wide range of industrial and commercial electronic applications.

• Effective EMI Noise Suppression: Helps attenuate common-mode noise in power lines and reduce electromagnetic interference in electronic circuits.
• Ferrite Magnetic Core: Provides magnetic characteristics suitable for common-mode filtering applications.
• Toroidal Winding Design: Supports common-mode impedance while helping maintain compact component dimensions.
• Through-Hole Mounting: Designed for PCB through-hole assembly, offering secure mechanical installation and convenient integration into electronic products.
• Compact Size: The T25×10×15 form factor is suitable for space-conscious power supply designs.
• OEM & ODM Customization: Inductance, winding specifications, lead configuration, and other parameters can be evaluated and customized according to your circuit requirements.

This toroidal common mode inductor can be used in a variety of electronic and electrical systems, including:

• Switching Mode Power Supplies (SMPS)
• AC-DC and DC-DC Power Supply Systems
• EMI and EMC Filter Circuits
• Industrial Control Equipment
• LED Drivers and Lighting Power Supplies
• Household Appliances and Consumer Electronics
• Electronic Equipment Requiring Power Line Noise Suppression

Note: Inductance, rated current, DC resistance, impedance-frequency characteristics, operating temperature, and other electrical parameters should be confirmed according to the specific product datasheet.

For OEM manufacturers, power supply developers, and electronic component distributors, selecting the right common mode choke is essential for balancing EMI performance, board space, assembly requirements, and production costs.

We support customers in selecting suitable ferrite core and winding configurations based on their circuit designs and application requirements.
