In the world of high-energy applications, reliability isn’t just a feature — it’s a fundamental requirement. From medical imaging systems to pulsed power supplies, pulse film capacitors are the silent workhorses behind every stable pulse. But what truly sets a pulse film capacitor apart in terms of reliability?

At CABO, we believe that reliability is not achieved by a single component, but through an integrated design philosophy — from the core material to the external case.

1. Dielectric Film: The Heart of Performance

The foundation of every reliable capacitor lies in its dielectric. Our PPA, PPC, PMS, and PPS series capacitors use carefully selected polypropylene and polyester films that offer exceptional dielectric strength, low loss, and long-term thermal stability. Combined with our proprietary film processing techniques, we achieve minimal defects and improved consistency across production batches.

2. Self-Healing Technology: Ensuring Safety & Longevity

A key feature across our pulse capacitor series is advanced self-healing capability. In the event of dielectric breakdown, localized faults are isolated without compromising the overall function, drastically reducing failure rates and extending service life — especially in demanding pulse discharge environments.

3. Pulse-Grade Metallization: For High dV/dt Reliability

High peak currents and fast voltage rise times demand superior metallization. Our pulse-grade zinc-aluminum metallized electrodes are engineered to withstand rapid charging and discharging cycles while maintaining stable capacitance, even under repeated pulse stress.

4. Encapsulation & Case: Protecting the Integrity

Whether it's plastic, resin-filled, or aluminum enclosures, each casing option in our PPA/PPC/PMS/PPS series is designed to match specific environmental and mechanical protection needs — including moisture resistance, thermal conductivity, and vibration resistance. For critical medical or military-grade systems, custom packaging is also available.

5. Rigorous Testing: No Room for Compromise

Before a single unit ships, every capacitor undergoes stringent in-house testing for high-voltage insulation, ESR, capacitance stability, and endurance under load.

Trusted by Industry Leaders Worldwide
