2N3055 Transistor

The 2N3055 is a silicon Epitaxial-Base Planar NPN Transistor. It is designed for power switching circuits.

L298N Dual Full Bridge Driver

A 15-lead flat package IC designed to accept TTL logic levels and drive inductive loads such as relays, solenoids, DC motors and stepping motors. Two inhibit inputs are provided to disable the device independently of the input signals

1 Farad Capacitor with Display

An electrolytic capacitor with an extremely large capacity (1 Farad) designed for demanding in-car audio systems. The capacitor is capable of delivering massive instantaneous currents to improve the crispness of bass. On the top of the capacitor is a housed display capable of showing information such as over voltage protection level, voltage level, etc. The capacitor has large, heavy duty, gold plated terminals and comes complete with fixing brackets.
