Kemet advances noise suppression solutions

Kemet has announced advancements to its FLEX SUPPRESSOR, a thin, flexible noise suppression sheet designed to reduce electromagnetic interference (EMI) and other noise disturbances.

The company's EFG3 and FS series now operate in a broader frequency range (up to 40GHz band), advancing FLEX SUPPRESSOR’s capabilities in 5G-connected devices and electronics for commercial, telecommunications, and automotive applications.

Made from Kemet's proprietary EMI-absorbent material, FLEX SUPPRESSOR sheets help prevent noise-induced impairments, malfunctions, and total system failure from occurring. The flexible polymer material houses micron-sized magnetic metal flakes that absorb unwanted radiated noise and convert it into heat.

Not only does the EFG3 and FS series absorb radiated noise, but they also prevent quasi-microwave range interference, electrostatic discharge, and desense in digital TV, 5G, WiFi, and Bluetooth devices.

The EFG3 and FS series are best suited for portable, connected devices and equipment that require a compact design, including mobile phones, digital cameras, and car infotainment systems.

FLEX SUPPRESSOR is a flexible sheet that can be cut into custom shapes for any design. It is also available in a flexible tape style and can replace bulky ferrite cores for noise suppression, allowing for smarter and more lightweight cable designs. The noise suppression tape is intended for charger, power, and interface cables used with commercial electronic devices, such as mobile phones and tablets.
