The NE555 is a square wave pulse generator module can be used to produce square wave signals for experimental development or in applications such as driving stepper motors, and as an adjustable pulse generator for microcontroller.
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 IRFB9N60A is a 600V 9.2A Third Generation HEXFETs from International Rectifier provide the designer with the best combination of fast switching, ruggedized device design, low on-resistance and cost-effectiveness.
The 2SK2837, 2SK-2837, K2837, 2837 is a 500V 20A N Channel Silicon Field Effect Transistor Or MOFET TO-3PN-3 Package. Chopper Regulator, DC−DC Converter and Motor Drive.
