RCA Connectors are coaxial connectors widely used in audio and video equipment, commonly found in household devices such as TVs, stereo systems, and DVD players.

There are two main types: red and white for stereo audio and yellow for composite video signal transmission. Designed for simplicity and low cost, RCA connectors are ideal for low-frequency analog signal transmission, typically operating within a range of 0 to 100 MHz.

While their use has decreased with the rise of digital interfaces, RCA connectors remain a standard in many home audio-visual setups.
