Common Mode Chokes

Eaton Common Mode Chokes feature a closed magnetic path that reduces conductive EMI emissions. These chokes feature robust construction, independent winding sections, and high-voltage isolation. The common mode chokes support inductance ranges from 5.5µH to 60,000µH and current ratings up to 7A, with low DCR for efficient operation. These chokes operate within the -40°C to 125°C (ECMT) and -40°C to 160°C (CMS) temperature ranges and comply with RoHS and halogen-free standards. Typical applications include industrial IoT equipment, power supplies, renewable energy systems, smart meters, medical devices, and consumer electronics.

WE-CMB Common Mode Power Line Inductors (Chokes)

Würth Elektronik WE-CMB Common Mode Power Line Inductors (Chokes) feature a compact design that delivers high suppression of asymmetric interferences, even at low-frequency ranges. In addition, these inductors provide broadband screening due to a low capacitance winding technique. Würth Elektronik WE-CMB Common Mode, Power Line Inductors, are ideal for power electronics and suppressing common-mode noises. Parasitics can have a significant effect on the noise attenuation and current rating of a common mode filter. Würth designed the WE-CMB series for minimal parasitic effects over its useful frequency bandwidth so it does what it is designed to do - get rid of the noise.

Battery Management Systems

Eaton provides a wide portfolio of products for Battery Management Systems (BMS), including terminal blocks, fuses, supercapacitors, chokes, inductors, and more. Battery Management Systems monitor individual cells, system voltage, current, and temperature. When monitoring individual cells, the BMS balances voltages and regulates the current flow, and if the upper or lower voltage, current, or temperature limit is exceeded, the BMS temporarily disconnects the load or source. Eaton Battery Management Systems estimate the State of Health (SoH), State of Charge (SoC), State of Energy (SoE), and State of Power (SoP) in batteries.
