Metallized Polypropylene Film Capacitor Axial Oval for AC and DC Circuits

Metallized polypropylene film capacitors are widely used in
AC and DC applications where low loss, high insulation resistance
and long-term reliability are required.
The TS04D axial oval series is designed to provide stable electrical
performance under high temperature and high voltage conditions.

Construction and Materials

The TS04D series uses metallized polypropylene film as both
dielectric and electrode.
The winding is encapsulated in flame-resistant plastic and sealed
with epoxy resin to enhance mechanical strength,
humidity resistance and thermal stability.

Electrical Characteristics

• Low dissipation factor for reduced power loss
• High insulation resistance for improved reliability
• Self-healing metallized structure
• Stable capacitance over temperature
• High dielectric strength

Key Specifications

• Operating temperature: -55°C to +100°C
• Capacitance range: 0.022?F to 47?F
• Capacitance tolerance: ±5% and ±10%
• Rated voltage: 250V to 1250V DC
• Withstand voltage: 1.7UR for 2 seconds

Design Advantages

The axial oval package provides compact volume
with high capacitance density,
making it suitable for space-constrained layouts.
The polypropylene dielectric ensures low dielectric loss,
which is critical in audio frequency circuits
and precision instrumentation.

Typical Applications

• Household appliance power circuits
• Instrumentation and measurement equipment
• Audio frequency and crossover networks
• DC link and filtering circuits
• AC coupling and timing circuits

Design Considerations

• Select voltage rating with appropriate derating margin
• Ensure thermal clearance in high ripple environments
• Use low-inductance layout for high frequency performance
• Avoid mechanical stress on axial leads

Conclusion

Metallized polypropylene axial capacitors provide
low loss, high reliability and stable capacitance
across a wide temperature range.
They are suitable for precision AC and DC circuits
requiring long service life and consistent performance.
