The JQC-3F (T73) 5V DC Power Relay is a compact and reliable electromagnetic relay designed for PCB mounting applications. This pack of five relays offers excellent value for hobbyists, engineers, and technicians working on automation, control systems, or electronics projects. Each relay operates on a 5V DC power source and is rated for 10A at 250VAC, making it well-suited for low power contact load switching tasks. The sealed construction helps protect the internal components against dust and environmental contaminants, ensuring consistent performance over time. With its standard JQC-3F T73 form factor, these relays are compatible with a wide range of common PCB layouts and circuit designs. The through-hole pin configuration allows for straightforward soldering onto circuit boards. Whether you are building a home automation system, working on an automotive control project, or prototyping an electronic device, these power relays deliver dependable switching performance. Having five units in a single order means you will have spares on hand for future builds or replacements. Please verify compatibility with your specific circuit requirements before installation.
