An IHCM common mode choke for high current commercial applications to 35 A has been introduced by Vishay Intertechnology.

Available with a low profile surface-mount construction, the Vishay Custom Magnetics IHCM-2321AA-10 is more robust than bulky toroid-based devices and delivers superior performance across temperature ranges to +155 °C.

With its low profile, the IHCM-2321AA-10 offers a reduced size and volume, making it more resistant to shock and vibration, while the enhanced core design extends current saturation out to as much as 35 A.

The choke is surface-mountable and compatible with automated pick and place assembly for increased flexibility in board layouts.

Along with excellent saturation characteristics, low DCR losses, and a 1500 VDC dielectric withstand voltage between coils, this device is ideal for commercial-grade DC/DC converters, EMI filters, and high current filters for noise suppression in motor control and other circuity in industrial and telecom applications.

In addition to the standard surface-mount configuration, the IHCM-2321AA-10 offers customisable inductance, impedance, DCR, and current ratings, along with through-hole mounting options.

The device is RoHS-compliant, halogen-free, and Vishay Green.
