Product Description
The Recom R-78HB5.0-0.5 Switching Regulator is a compact, high-efficiency DC-DC voltage converter designed to provide a steady 5V DC output from a wide input range of 9V to 72V DC. This device is suited for electronic circuit applications where a reliable, regulated 5V supply is essential.
With a power rating of 2.5W and maximum output current of 500mA, this switching regulator is optimized for both instrumentation and automotive electronics. The through-hole mounting style and SIP (Single Inline Package) format enable rapid and secure PCB integration, making it suitable for industrial and laboratory builds.
The high efficiency of up to 81% ensures minimal heat generation during operation, reducing cooling requirements and energy consumption. Additionally, its flame retardant housing and integrated continuous short circuit protection and thermal shutdown mechanisms enhance operational safety and device longevity.
Its dimensions (11.5mm length x 8.5mm width x 17.5mm height) allow for installation within limited PCB space, and the output ripple is kept low by an integrated 1µF capacitor. The regulator maintains stability under varying load conditions, with line regulation of ±1% and load regulation of ±0.6%.
Applications include automotive, industrial, and instrumentation equipment requiring robust voltage conversion. The product is well-suited for scenarios demanding high reliability and operational safety, such as circuit boards in sensors, controllers, and control panels.
The Recom R-78HB5.0-0.5 features RoHS compliance and an MTBF of 7,395,000 hours, testifying to its reliability and quality for commercial and technical use. Its protective plastic body prevents electrical shocks and contributes to its high safety rating.
This device is widely used in environments where vibration resistance and secure connections are valuable, and its flame retardant properties ensure regulatory compliance. Typical industrial use cases span manufacturing automation, automotive electronics, laboratory instrumentation, and commercial circuit design.
