DC power jack module

DC power jack module


The DC Power Jack Module is a component used to provide a stable DC power input to electronic circuits and devices. It is typically used to connect external power sources, such as batteries or adapters, to a circuit board. The module often includes a DC power jack, associated connectors, and sometimes voltage regulation or protection features.

Key Features:

  • Connector Type: DC power jack (commonly 2.1mm or 2.5mm barrel connector)
  • Input Voltage Range: Typically 5V to 12V (varies by module)
  • Current Rating: Varies, commonly up to 2A or 5A
  • Mounting Type: Through-hole or surface-mount
  • Protection: Some modules include built-in protection against over-voltage and reverse polarity
  • Additional Features: May include voltage regulators or filter capacitors

Technical Specifications:

  • Connector Size: Standard barrel jack size, usually 2.1mm or 2.5mm outer diameter
  • Voltage Range: 5V to 12V (depends on specific module)
  • Current Rating: Typically up to 2A or 5A
  • Pin Configuration: Usually includes positive (center pin) and ground (outer sleeve) connections
  • Dimensions: Varies by module, typically small form factor


  • Power Supply Input: Provides a reliable input for powering electronic projects and circuits.
  • DIY Electronics: Commonly used in custom electronic devices and hobby projects.
  • Prototyping: Useful for breadboards and prototype boards to connect external power sources.
  • Power Management: Integrates with other power management components like regulators and filters.

For detailed technical information, refer to the datasheet of the specific DC power jack module you are using, as specifications can vary based on the design and manufacturer.
