Overview

The G5V-2-H1-DC5 is a high-sensitivity, through-hole low signal relay designed for switching loads up to 1A. This DPDT (2 Form C) relay features a 150mW high-sensitivity coil, making it ideal for circuits with limited drive current in telecommunication and security applications.

Why Choose This Part

The G5V-2-H1-DC5 offers a high-sensitivity coil that requires less actuation current than standard G5V-2 models, reducing heat and power requirements. Its compact 20.5mm x 10.1mm DIL footprint allows for high-density PCB layouts while maintaining 1A switching capability across two poles.

Applications

Telecommunication Switching
Ideal for routing signals in PABX systems and central office equipment due to its DPDT configuration and high sensitivity.
Security Control Panels
Reliable switching for alarm loops and notification circuits where low power consumption is critical for battery backup life.
Test and Measurement
Used in automated test equipment to switch low-level signals with minimal thermal EMF and reliable contact resistance.
Smart Home Hubs
Integrates into low-voltage control circuits for home automation tasks such as thermostat signaling or low-power lighting control.

Getting Started

When designing with this relay, ensure the driving transistor or MCU GPIO (via a buffer) can provide the 30mA coil current at 5VDC. Always include a flyback diode across the coil pins to protect sensitive control electronics from inductive voltage spikes during turn-off.
