G5Q-14-DC12
Overview
The G5Q-14-DC12 is a compact, subminiature power relay from Omron designed for high-capacity switching on PCBs. It features a SPDT (1-Form-C) contact arrangement and is capable of handling switching currents up to 10A while maintaining a small footprint for dense board layouts.
Why Choose This Part
The relay offers high insulation resistance and an impressive 105C maximum operating temperature, making it suitable for thermally demanding environments. Its sealed construction protects contacts during wave soldering and cleaning processes, while the 12VDC coil is optimized for low power consumption at 33.3mA.
Applications
Getting Started
To drive this relay from a microcontroller, use a NPN transistor or MOSFET as a low-side switch along with a flyback diode (e.g., 1N4007) across the coil to prevent inductive voltage spikes. Ensure PCB traces for the 10A load are sufficiently wide and use high-ounce copper to manage thermal rise.
