parasitic capacitance

Parasitic capacitance refers to an unintended, small electrical storage capability that occurs naturally between components or parts of a circuit, even when not designed to act as a capacitor. It happens because nearby conductive parts can hold a tiny charge, similar to how a capacitor works, which can affect circuit performance by causing unwanted noise, signal delay, or energy loss. Although usually minimal, parasitic capacitance is an important consideration in designing high-speed or sensitive electronic systems to ensure they operate accurately and reliably.
