EMI Filter Chokes (Toroidal Coils)
There are three basic forms for these EMI filters:
EMI filter without base, with vertical base or horizontal base.
The below drawing shows EMI filter without base.
Applications: Features
- Power supplies.
- Switching circuits.
- SCR and triac controls.
- Output chokes.
- EMI/RFI chokes.
- Other filters.
- Useful in a wide variety of power conversion.
- Wound on iron powder material toroids.
- Cost effective design.
- Low volume hand wound to high volume automatic
machine wound available- 130 °C or l55 °C(UEW-NY) or 180 °C(PEW-H) wire.
- High saturation current.
- Coated with varnish or UL tube.
Characteristics Ordering information:
- Inductance range:
1.0uH to 10000uH- Current rating: about 8.0A/mm
