X2 Film Capacitors for Across-the-Line EMI Suppression

Class X2 film capacitors are designed for across-the-line applications where suppression of electromagnetic interference is required.
They are commonly connected between line and neutral to attenuate differential-mode noise while maintaining safety compliance for mains operation.
The TS08H series supports this function across a wide capacitance range and extended operating temperature conditions.

Operating Conditions

For equipment connected directly to the AC mains, the capacitor must maintain stable performance under continuous voltage stress and varying environmental conditions.
The TS08H series operates within a temperature range of -40°C to +100°C, supporting both indoor and industrial environments.

• Operating temperature: -40°C to +100°C
• Capacitance range: 0.0047 ?F to 10 ?F
• Designed for across-the-line connection

Role in EMI Suppression Circuits

In power supply input stages, X2 capacitors work with inductive components to form EMI filters.
They reduce conducted noise generated by switching devices and improve compliance with electromagnetic compatibility requirements.

• Attenuates differential-mode noise
• Used in AC input EMI filters
• Supports stable operation of power electronics
• Compatible with safety-rated mains circuits

Applications

• Switching power supplies
• Home appliances
• Industrial equipment
• Lighting drivers
• AC-powered electronic systems

Design Considerations

• Select capacitance based on required EMI attenuation
• Verify temperature range for target environment
• Ensure compliance with across-the-line safety requirements
• Consider interaction with common-mode chokes and filter topology
