The HA17339A is comparators designed for use in power or control systems. Its operate from a single power-supply voltage over a wide range of voltages, and feature a reduced power-supply current since the power-supply voltage is determined independently.
The TIP42C is a base island technology PNP power transistor in TO-220 plastic package that make this device suitable for audio, power linear and switching applications. The complementary NPN type is TIP41C.
The SMD Tri-Color (RGB) LED Module Full Color LED Module Tri-color LED for Arduino. Can be directly plugged into the Arduino motherboard, no DuPont line connection required.
The 2SC4977 is a 400V, 7A, Silicon NPN Power Transistor. A NPN transistor is a type of bipolar junction transistor (BJT) that consists of two p-type semiconductor materials separated by a single n-type material.
