CarXield Power EMC Filters

The TDK Corporation CarXield (B84252*) is a standardized EMC filter series for 500 V and 1000 V automotive inverters that can significantly reduce development time for system integrators. These filters enable rapid market entry for mid-sized e-mobility manufacturers with validated, compact EMI solutions that meet automotive standards and are immediately available through streamlined, standardized manufacturing processes. By mitigating inverter-to-battery interference, CarXield filters enhance overall powertrain EMC performance and simplifies compliance for electric drive applications.

Designed to suppress inverter-generated noise on battery lines, which is crucial for both electromagnetic immunity and emission compliance, CarXield power EMC filters ensure stable performance in xEV platforms. The components measure 140 mm x 59 mm x 50.0 mm (L x W x H) and cover 500 V and 1000 V systems with rated currents of up to 400 A at ambient temperatures of +85°C, and transient peak currents up to 1000 A. The typical DC resistance is just 0.1 mΩ. Based on nanocrystalline core technology and incorporating X2 or Y2 class capacitors with integrated passive discharge, these filters are engineered for durability under severe ambient conditions.

Thanks to its availability with or without copper busbars and optional passivated finishes, CarXield filters support flexible system integration, allowing developers to adapt thermal and spatial designs without compromise. They are certified to automotive standards such as AEC-Q200 and validated against MBN LV 124 profiles.
