Nanocrystalline Common Mode Chokes

Pulse Electronics Nanocrystalline Common Mode Chokes (CMCs) are designed to filter out common mode Electromagnetic Interference (EMI) noise in AC/DC, DC/DC, and DC/AC circuits. The amorphous core enables the high impedance per volume, which minimizes board space while maximizing common-mode noise rejection. These CMCs block high-frequency alternating currents and allow low-frequency direct currents to pass through electrical circuits. The chokes feature high impedance per unit volume and stable impedance over a wide temperature range. Typical applications include AC/DC power supply, motor drives, smart grid, Electric Vehicle (EV) charging, and power generation.
