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
- 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.
