1000pF 100V ±5% C0G/NP0 PTH Ceramic Capacitor

Jargon buster

Plain-language definitions for the technical terms used above.

capacitance

Capacitance is the amount of electrical charge a capacitor can store, usually measured in farads such as uF. Choosing the right capacitance value matters because it affects how well a circuit filters power, handles timing, or stores short bursts of energy.

PCB

A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.

RF

RF means radio frequency, referring to signals used for wireless communication and other high-frequency electronics. A low-noise, stable power supply is important for RF circuits because power noise can affect signal quality and measurements.

through-hole

A mounting style where the component leads pass through holes in a circuit board and are soldered on the other side. Through-hole parts are often easier to handle and solder by hand, which is useful for classroom and hobby projects.

Tolerance

Tolerance tells you how far the real resistance value may be from the printed value. A 1% resistor is useful when a circuit needs more predictable behaviour than a looser 5% or 10% part.
