TS04S double-sided metallized polypropylene axial film capacitor for high-voltage, low-loss power electronics.

This guide explains why the TS04S double-sided metallized polypropylene axial capacitor behaves as a non-polar film capacitor and how it can be used safely in AC and pulse circuits. It is written for design engineers, distributors and OEMs who need reliable axial film capacitors for high-dielectric strength applications.

1. Why Non-Polar Axial Film Capacitors Matter

Polypropylene film capacitors with double-sided metallization, such as the TS04S, are inherently non-polar. The dielectric is an insulating polypropylene film, and the electrode layers are applied on both sides of the film, so there is no “positive” or “negative” terminal required for normal operation.

• Support for AC and bidirectional pulse signals without reverse-voltage damage
• Stable capacitance and low ESR over time
• Reduced assembly errors and simplified PCB layout (no polarity marking required)
• Long service life and strong thermal resilience compared with many electrolytics

In applications where the voltage reverses or the waveform is symmetrical (AC coupling, snubber networks, timing circuits), non-polar film capacitors like TS04S are a safer and more predictable choice than polarized capacitors.

2. Technical Advantages and Cross-Brand Compatibility

The TS04S series is available across a broad voltage range and multiple can sizes, which gives distributors and OEMs flexible stocking options and easier cross-reference mapping against other brands.

• High-voltage PP axial options for demanding power electronics
• Double-sided metallization supports controlled self-healing at localized faults
• Low dielectric loss suitable for precision and high-frequency circuits
• Cross-brand replacement lists and datasheets available for sourcing and qualification

For distributors, this means one TS04S family can cover multiple part numbers from other manufacturers, while maintaining consistent electrical performance and mechanical fit.

3. Applications Optimized for TS04S

Typical use cases where TS04S non-polar axial film capacitors are especially effective:

• Timing circuits and pulse shaping where low loss and stable capacitance are critical
• SMPS, LED drivers and inverters using high-voltage, high-frequency switching
• AC filtering and snubber networks across relays, SCRs and power semiconductors
• Precision and industrial-grade circuits requiring long-term stability and low drift
