Connector may refer to: Plumbing Electrical connector, a device for joining electrical circuits together (sometimes known as ports, plugs, or interfaces)
Fan is a machine for producing airflow, often used for cooling.
Igbt Module is a semiconductor device that combines the high-speed switching performance of a power MOSFET with the high-voltage/high-current handling capabilities of a bipolar transistor.
A relay is an electrically operated switch. It consists of a set of input terminals for a single or multiple control signals, and a set of operating contact terminals. The switch may have any number of contacts in multiple contact forms, such as make contacts, break contacts, or combinations thereof.
