G5Q-1A4-EU DC5

Overview

The G5Q-1A4-EU DC5 is a compact, high-capacity power PCB relay designed for switching heavy loads in space-constrained applications. It features a SPST-NO contact configuration and is rated for operation in high-temperature environments up to 105 degrees Celsius. This sealed relay is particularly well-suited for household appliances and building automation systems that require a 5VDC coil voltage.

Why Choose This Part

This relay offers a high switching capacity in a small footprint of 20.3mm by 10.3mm, optimizing PCB real estate. Its sealed construction provides protection during soldering and cleaning processes, while the 105C temperature rating ensures reliability in thermally demanding enclosures.

Applications

Getting Started

To integrate this relay, ensure the driving circuit can provide at least 40mA at 5VDC for the coil. Use a flyback diode (such as a 1N4007) across the coil pins to protect the driving transistor from inductive spikes. Verify that PCB trace widths for the NO and COM terminals are sized appropriately for the intended load current to prevent overheating.
