A capacitor used for providing a comparatively low impedance A-C patharound a circuit element.

a capacitor that provides low impedance over certain (high) frequencies

a capacitor serving as a virtual power supply that supplies electrical charge to an integrated circuit from the vicinity of the integrated circuit

A capacitor so wired in a circuit that it has low reactance for signal frequencies and, hence, effectively shunts them around another component.

A capacitor used for providing a comparatively low impedance AC path around a circuit element.

A capacitor used to provide an AC ground at some point in a circuit.

A capacitor that is used to establish an AC ground at a specific point in a circuit.
