WURTH ELEKTRONIK 744821240 Common Mode Choke

The WE-CMB series offers high suppression of asymmetric interference, even at low frequencies. Designed to minimize parasitic effects common in standard common mode chokes, these units feature an optimal core-to-winding ratio to handle high currents within a compact form factor. The winding technique ensures broadband screening with low capacitance, resulting in effective interference reduction across a wide frequency range. Suitable for power management and motor drive applications, they operate in temperatures from -40°C to +125°C. Custom designs are available, but high demand may extend lead times. Not eligible for discounts.
