Vishay Intertechnology has introduced two new low-profile common mode chokes—ICMS2321-10 and ICMS2321-1A—targeted for high current applications in automotive, energy, and industrial sectors. These chokes are available in both surface-mount and through-hole packages, supporting currents up to 30 A and providing a dielectric withstand voltage of 1500 V DC.
Key Features:
- Low Profile Design: More resistant to shock and vibration.
- High Temperature Performance: Operates at temperatures up to +150 °C due to enhanced core design.
- Rugged Construction: Ideal for applications such as DC/DC converters, high voltage inverters, EMI filters, and motor control noise suppression.
- AEC-Q200 Qualified: The ICMS2321-1A is suitable for automotive on-board chargers.
Customizable Options:
- Inductance, impedance, DCR (DC resistance), and current ratings can be tailored.
- Surface-mount versions are available on tape and reel, compatible with automated assembly.
