MALVERN, Pa. - Sep. 1, 2026 - Vishay Intertechnology, Inc. (NYSE: VSH) today introduced two new low profile common mode chokes for high current automotive, energy, and industrial applications. Available in both surface-mount and through-hole packages, the Vishay Dale commercial ICMS2321-10 and Automotive Grade ICMS2321-1A combine a heat rating current to 30 A with a 1500 VDC dielectric withstand voltage between coils.
With their low profile, the devices released today offer a reduced size and volume, making them more resistant to shock and vibration, while their enhanced core design increases performance and saturation current at high temperatures up to +150 °C. Offering a self-shielded, rugged construction, the common mode chokes are ideal for DC/DC converters, high voltage inverters, EMI filters, and high current filters for noise suppression in motor control and other circuitry. The AEC-Q200 qualified ICMS2321-1A is well suited for use in automotive on-board chargers.
In addition to their surface-mount and through-hole mounting options, the ICMS2321-10 and ICMS2321-1A offer customizable inductance, impedance, DCR, and current ratings. Devices with surface-mount terminations are available in tape and reel packaging and are compatible with automated pick and place assembly for increased flexibility in board layouts. The common mode chokes are RoHS-compliant, halogen-free, and Vishay Green.
