Kemet Electromagnetic Compatibility

Communication choke coil

KEMET AC choke can be used for common mode, normal mode, and dual-mode. They are composed of multiple core materials, allowing various shape factors and magnetic permeability levels to attenuate noise in a wide or concentrated frequency band.

DC choke coil

A DC choke uses magnetic flux to block certain frequencies by passing current through the coil. KEMET's combination of common mode and normal mode choke coils is suitable for a wide range of applications, including household appliances and industrial equipment.

EMI/RFI filter

KEMET provides a wide range of power feed through EMI filters to minimize high-power transient interference caused by switching elements in power generation systems.

pulse transformer

Pulse transformer is a specially designed common mode choke that can filter out EMI current from power transformers or analog front-end of modems in power line communication. Pulse transformers support up to 264 VAC and low insertion loss starting from 1 MHz, making them an effective solution that complies with EMI regulations while allowing the required signals to pass through unaffected.

EMI core

KEMET offers a variety of ferrite cores in different shapes and sizes to help filter out low-frequency, mid frequency, and high-frequency noise. In addition to accommodating flat and circular cables with ferrite cores, there are also AEC-Q200 compliant components to meet your automotive needs.

Ferrite Bead 

KEMET's unique multi-layer ferrite structure provides higher reliability and minimizes heat generation when filtering high-frequency noise. Our ferrite beads are suitable for signal and power lines, typically used in space limited applications such as wearable devices or PCs.

Ferrite material

KEMET ferrite materials are designed specifically for wireless power transmission applications. These materials have low magnetic core losses over a wide temperature range, effectively concentrating and shielding magnetic flux to achieve correct wireless power transmission. Customized solutions can also be provided.

Elastic suppressor ®

These fast and easy to install flexible noise suppression boards are designed to alleviate EMI noise and reduce sensitivity reduction caused by radiation in RF circuits. Flex Suppressor improves wireless power transmission and near-field communication circuits, such as RFID. We can also provide products that comply with the AEC-Q200 standard.
