Sectional common node chokes differ from bifilar common mode chokes in construction and EMC application uses.
Bifilar common mode choke attributes:
- Less differential impedance
- High capacitive coupling
- Less leakage inductance
Sectional common mode choke attributes:
- Low capacitive coupling
- High leakage inductance
Bifilar common mode choke EMC applications:
- Data lines
- Sensor lines
- USB
- HDMI
Sectional common mode choke EMC applications:
- Power supply input/output filter
- Switching power supply decoupling
