The C44P-T capacitor is a polypropylene metallized film capacitor with a cylindrical, aluminum can-type design filled with a soft, vegetable oil-based, polyurethane resin. It uses high current screw terminals, a metal deck with plastic insulators, and an overpressure safety device.

The C44P-T wasn’t developed to outperform competitors in the lab—it was engineered to survive the worst conditions the real world can throw at a capacitor. Instead of assuming mild operating environments, the C44P-T is designed to withstand extremes. It operates continuously at temperatures of up to 90°C for 12,000 hours. At 85°C, it has a lifespan of 100,000 hours, and at 70°C, it can exceed 250,000 hours at rated voltage. That’s decades of continuous use in systems expected to operate with little to no human intervention. But it’s not just about withstanding heat. The C44P-T is qualified to THB Grade IIIB standards, 85°C, 85% relative humidity, for 1,000 hours at rated voltage. Most capacitors struggle in this space. The C44P-T thrives.

For engineers, this means no more compromises between performance and resilience. You can now design for efficiency and long-term reliability simultaneously.
