Vishay Intertechnology IHCM Common Mode Choke Offers Low Profile, High Shock and Vibration Resistance for 35 A Commercial Applications
2021-12-08 | 반환
MALVERN, Pa. — Dec 8, 2021 — Vishay Intertechnology, Inc.today introduced a new IHCM common mode choke for high current commercial applications to 35 A. Available with a low profile surface-mount construction, the Vishay Custom Magnetics IHCM-2321AA-10 is more robust than bulky toroid-based devices, while delivering 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 IHCM-2321AA-10 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, the IHCM-2321AA-10 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 customizable inductance, impedance, DCR, and current ratings, along with through-hole mounting options. The device is RoHS-compliant, halogen-free, and Vishay Green.
