EMI / RFI Suppression | Farnell® UK

At Farnell, we offer a broad range of EMC and RFI suppression components designed to minimize electromagnetic interference (EMI) and ensure stable performance in electronic systems. These components help maintain signal integrity, reduce unwanted noise, and meet industry compliance standards.

Our selection includes:

Common Mode Chokes and Filters: Block high-frequency noise while allowing desired signals to pass, ideal for controlling noise from sources like motors and inverters.
EMI Noise Filters: Extract unwanted currents from cables and wiring, protecting circuit functionality.
Ferrites: Ferrite beads and sleeves suppress high-frequency noise in circuits, commonly used in computer monitors, medical devices, and data cables.
Filtered IEC Power Entry Modules: Compact solutions combining inlet connectors with EMI filters to minimize interference at equipment entry points.
Low Voltage Suppression Filters: Ensure stable signal transmission in low-voltage applications, suppressing EMI in computers and peripherals.
Power Line Filters: Attenuate RFI between power sources and equipment circuitry, crucial for noise reduction in mains-powered devices.
Shielding Gaskets and Materials: Block external EMI or contain internal noise in electronic enclosures, essential for interference control.

Farnell’s EMC/RFI suppression components are suited for a wide range of applications in consumer electronics, automotive systems, industrial controls, and telecommunications. Select from our range to enhance your designs with reliable noise control and interference suppression.
