310VAC Metallized Polypropylene Film Capacitors for Capacitive Divider Applications

Overview

The TS08A metallized polypropylene film capacitor is designed for capacitive divider circuits connected in series with 100 to 240 VAC mains.
Its polypropylene dielectric and X2 safety class structure support stable AC operation in non-isolated power supply topologies.

Electrical Characteristics

• Rated voltage: 310 VAC
• Capacitance range: 0.0022 ?F to 2.2 ?F
• Capacitance tolerance: ±10%
• Operating temperature: ?40°C to +110°C
• Testing voltage: 4.3 UR DC for 60 seconds

Dissipation Factor

• 0.0010 ?F ? CR ? 0.47 ?F: ?0.1% (1 kHz, 20°C)
• 0.47 ?F ? CR ? 1.0 ?F: ?0.2% (1 kHz, 20°C)
• 1.0 ?F ? CR ? 10 ?F: ?0.3% (1 kHz, 20°C)

Insulation Resistance

• CR ? 0.33 ?F: ?15,000 MΩ
• CR > 0.33 ?F: ?5,000 S (20°C, 100 V, 1 min)

Performance in Capacitive Divider Circuits

Capacitive divider power supplies use the reactance of film capacitors to limit current from the AC mains without a transformer.
Stable capacitance, low loss, and reliable insulation are required to maintain predictable output and long-term operation.

Applications

• Energy meter circuits
• Small LED driver modules
• Household appliance control panels
• Thermostats
• Transformerless capacitive power supplies

Design Considerations

• Verify X2 safety class compliance for mains connection
• Calculate reactance based on capacitance and line frequency
• Ensure proper discharge resistor in capacitive dropper designs
• Maintain creepage and clearance for AC mains operation
