G5Q-1A4 DC12
Overview
The G5Q-1A4 DC12 is a compact, high-performance SPST-NO (1 Form A) power relay designed for switching loads in space-constrained applications. It features a 12VDC coil that draws approximately 16.7 mA and provides full sealing for compatibility with automated soldering and cleaning processes.
Why Choose This Part
This relay offers a fast 10 ms operate time and a 5 ms release time, ensuring responsive switching for control circuits. Its fully sealed construction protects contacts from harsh environments, while the high sensitivity coil reduces power consumption in 12V control logic.
Applications
Key Specifications
Getting Started
When designing with this through-hole relay, ensure adequate trace widths for high-current loads and include a flyback diode (such as a 1N4007) across the coil pins to protect driving transistors from inductive spikes. Verify that the PCB layout accounts for the specific pin pitch of the G5Q footprint to maintain proper creepage and clearance distances.
