The 940C10P series from Cornell Dubilier Electronics is a line of axial film capacitors rated for 1000V. These capacitors are designed for high-voltage applications where stability and reliability are crucial. They show up frequently in power supplies, motor drives, and other industrial electronics where voltage spikes and surges are common.

One thing worth noting is their excellent temperature stability. Engineers tend to reach for these when they need a capacitor that can handle wide temperature ranges without degrading performance. Another practical benefit is their low ESR (Equivalent Series Resistance), which minimizes power loss and helps maintain system efficiency. If you're working on any project involving high-voltage filtering or smoothing in power electronics, these capacitors are a solid choice due to their robust design and reliable performance under various conditions.
