G5Q-1A4-DC5

Overview

The G5Q-1A4-DC5 is a compact, high-capacity SPST-NO power PCB relay capable of switching loads up to 10A. It operates with a 5VDC coil voltage and features a sealed construction to protect against environmental contaminants during soldering and operation. This relay is designed for efficient power management in space-constrained applications requiring reliable mechanical switching.

Why Choose This Part

This relay offers a high switching capacity of 10A within a small footprint, providing excellent power density. Its sealed design allows for automatic cleaning processes after soldering and ensures long-term reliability in humid or dusty environments. With a low coil power consumption of approximately 400mW, it is suitable for energy-efficient control boards.

Applications

Getting Started

When integrating this relay, ensure the driving transistor or MCU pin can handle the 80mA coil current, typically requiring a flyback diode to protect against inductive spikes. Maintain proper creepage and clearance distances on the PCB layout between the low-voltage DC coil pins and the high-voltage AC load traces. Refer to the footprint specifications for the 4-pin PCB layout to ensure correct pad spacing for the SPST-NO configuration.
