G5V-2-H1 DC5
Overview
The G5V-2-H1 DC5 is an ultra-sensitive, DPDT (2 Form C) low-signal relay designed for high-density mounting. This through-hole relay features a 5VDC coil and is fully sealed to withstand soldering and cleaning processes. It is specifically engineered for switching small signals in telecommunications and peripheral equipment where low power consumption is critical.
Why Choose This Part
The H1 variant is an ultra-sensitive model with a low 150mW nominal power consumption (30mA at 5VDC), making it suitable for energy-efficient designs. Its bifurcated crossbar contacts ensure high contact reliability for switching loads as low as 10mVDC, and the fully-sealed DIP package protects the internals from environmental contaminants.
Applications
Key Specifications
Getting Started
To integrate this relay, ensure your PCB layout accommodates the 2.54mm pitch 8-pin DIP footprint. Since it is a non-latching relay, the coil must remain energized to maintain the operated state. Use a standard flyback diode (such as a 1N4148) across the coil pins to protect your driving transistor or MCU from inductive voltage spikes during turn-off.
