5.5mm DC Barrel Power Jack, Panel Mount

A DC barrel jack gives a project a standardized, reliable way to accept power from an external wall adapter or power brick, using the same 5.5mm barrel connector standard found on countless consumer and hobby electronics power supplies rather than requiring a custom connector or bare wire terminal that's easy to wire backwards.

Rated for 30V at 0.5A, this jack covers the common low-to-moderate power range used by most small driver boards, LED controllers, and similar low-current electronics - genuinely matching the power delivery range of a typical small wall-wart adapter rather than being oversized for the application. Contact resistance is rated low (0.03 ohms) for minimal voltage drop at the connection point, and insulation resistance is rated at 100 megohms, giving solid electrical isolation between the connector's positive and negative paths.

Mechanical construction includes a rated withstand voltage of 500V AC for one minute and a 5000-cycle insertion/removal life rating, reasonable durability for a connector that gets plugged and unplugged repeatedly over a product's service life. Operating temperature range spans -40 to 55C, giving headroom beyond typical indoor use.

Builders designing a driver board, LED controller, or any small electronics project that needs to accept power from a standard external wall-adapter power supply rather than requiring a custom power connector will find this 5.5mm barrel jack a well-proven, standard component for that connection.
