Inverter noise in electric vehicles can slow development. See an EMC filter that reduces interference, speeds up integration, and helps keep drivetrains compliant.
TDK Corporation have introduced CarXield, a standardized EMC filter series for automotive inverters rated at 500 V and 1000 V. CarXield reduces interference between inverters and batteries, improving powertrain EMC performance and simplifying compliance for electric drivetrains. Its main applications include EMI noise reduction in the electric drivetrain of commercial and passenger vehicles, enabling mid-sized e-mobility manufacturers to bring vehicles to market faster.
The filters help system integrators cut development time with validated, compact EMI solutions that meet automotive standards. They are designed to suppress inverter-generated noise on battery lines, ensuring both electromagnetic immunity and emission compliance in xEV platforms.
CarXield components measure 140 × 59 × 50 mm (L × W × H) and cover 500 V and 1000 V systems with rated currents up to 400 A at ambient temperatures of +85 °C, and transient peak currents up to 1000 A. The typical DC resistance is 0.1 mΩ. Using nanocrystalline core technology and incorporating X2 or Y2 class capacitors with integrated passive discharge, the filters are engineered to withstand severe ambient conditions.
Some of the key features of EMC filter series include:
- Standardized solution for xEV powertrains
- Tailored for the dynamic needs of mid-sized e-mobility manufacturers
- Based on nanocrystalline cores and X2 and Y2 capacitors
- Passive discharge circuit
- Easy and fast to install
- Compact design
Available with or without copper busbars and optional passivated finishes, CarXield allows flexible system integration, making it easier for developers to adapt thermal and spatial designs without compromise. The filters are certified to automotive standards such as AEC-Q200 and validated against MBN LV 124 profiles.
