Efficient Noise Suppression – VACOCOILImproved Attenuation at High Frequency
Common Mode Chokes (CMCs) with the patented VACOCOIL design offer improved attenuation at high frequency (f > 1 MHz) compared to standard designs.
Benefits:
- 10x improved impedance compared to standard design (@10 MHz)
- Optimized for high current applications
- Cost-optimized design
