Key Features & Applications
- Dual Safety Rating: Meets the stringent X1 (up to 4kV impulse) and Y1 (up to 8kV impulse) requirements, making it suitable for direct connection to the AC mains.
- High Reliability: Designed for continuous operation in interference suppression and "line bypass" applications where safety is critical.
- Self-Extinguishing: The specialized epoxy coating ensures the component does not become a fire hazard in the event of a failure or surge.
- Common Applications:
- EMI/RFI filtering at the power entry stage.
- Across-the-line suppression (Class X).
- Line-to-ground (chassis) bypass (Class Y).
- Industrial power supplies and high-voltage lighting ballasts.
