G5Q-1A4-EU DC12
Overview
The G5Q-1A4-EU DC12 is a high-capacity, fully sealed SPST-NO (1 Form A) general purpose power relay from Omron. It features a 12VDC coil with a low 16.7 mA operating current and is designed for reliable switching in compact PCB layouts. This 'EU' variant is specifically optimized for high-capacity loads while maintaining a small footprint of 20.3mm by 10.3mm.
Why Choose This Part
This relay offers a sealed construction that protects against flux and environmental contaminants during soldering and operation. It provides a fast 10 ms operate time and 5 ms release time, ensuring responsive switching. The 16.7 mA coil current at 12VDC reduces power consumption and heat dissipation in dense control boards.
Applications
Key Specifications
Getting Started
To integrate this relay, ensure the PCB footprint matches the 2.54mm pitch for through-hole mounting. A standard NPN transistor or logic-level MOSFET circuit is recommended to drive the 16.7 mA coil current from a microcontroller. Always include a flyback diode (such as a 1N4007) across the coil terminals to protect against inductive spikes during de-energization.
