EMC Filters
TE Connectivity's EMC Filters are designed to reduce unwanted electromagnetic interference (EMI) and electrical noise on power and signal lines. They help electronic systems meet EMC requirements by attenuating unwanted high-frequency noise while allowing the required electrical signals or power to pass through.
Key Highlights
- Designed for EMI/EMC noise suppression in electronic and electrical systems.
- Helps improve electromagnetic compatibility and system reliability.
- Available for power, signal, data, and communication interfaces depending on application.
- Can be integrated into connectors, cable assemblies, PCBs, or equipment interfaces.
- Suitable for demanding automotive, industrial, aerospace, medical, and communication applications.
- Supports filtering of common-mode and differential-mode noise.
- Designed for application-specific electrical, mechanical, and environmental requirements.
TE Connectivity's EMC filter solutions use filtering components and technologies to suppress unwanted electrical noise generated by electronic circuits, motors, switching power supplies, and other sources.
Depending on the design, EMC filters can incorporate components such as capacitors, inductive elements, common-mode chokes, feedthrough filtering elements, and connector-integrated filtering technologies. The appropriate filter configuration is selected based on the required frequency attenuation, voltage/current rating, signal characteristics, and installation environment.
