C1124 Transistor Datasheet Better 〈Validated · 2027〉
The C1124 (often referred to as the 2SC1124) is a high-voltage NPN silicon planar transistor primarily designed for AF (audio frequency) power amplification and switching applications. Originally manufactured by Sony, this transistor is known for its reliability in vintage audio equipment, such as driver boards for classic stereo receivers. Core Specifications of the
