4700uF 10v Electrolytic 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.

electrolytic capacitor

An electrolytic capacitor is a type of capacitor that can store relatively large amounts of electrical charge in a small package. It is commonly used for smoothing power supplies, reducing noise, and short-term energy storage, but it usually has polarity so it must be installed the correct way around.

LED

A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.

servo

A servo is a motor with built-in position control, usually told to move to a specific angle by a control signal. It matters when you need repeatable movement, such as steering, arms, flaps, or linkages, rather than continuous spinning.

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.
