Your circuit needs a small, stable capacitance at 100VDC and you don't want to babysit a component that drifts after a few months on the shelf. This miniature metallised polyester cap from Jaycar is built for exactly that: long-term stability in a tiny package. It handles 1nF at 100VDC, gives you good mechanical solidity, and costs less than you'd pay for a film alternative of equal spec. It's the go-to general-purpose capacitor when you need predictable behaviour without over-engineering the bill of materials
