The 930C4P series from Cornell Dubilier is a line of film capacitors designed for a wide range of capacitance values, all rated at 400V. These components are commonly found in power supplies, filtering circuits, and energy storage applications due to their robust voltage rating and reliable performance.

If you're working on high-voltage filtering or decoupling circuits, these capacitors are a go-to choice. They provide excellent stability and reliability, making them ideal for environments where voltage spikes and fluctuations are common. One thing worth noting is that engineers tend to reach for this series when they need a compact solution that can handle high voltages without compromising on capacitance value.

Another practical application is in power factor correction circuits, where the 400V rating ensures safe operation even under peak conditions. The film construction also offers good temperature stability, which is crucial in maintaining consistent performance across different operating temperatures.

Overall, the 930C4P series is a versatile and reliable option for engineers looking to integrate robust capacitors into their designs without sacrificing space or performance.
