Recom Switching Regulator Through Hole 3.3V DC Output Voltage 72V DC Input Voltage 500mA Output Current R-78HB3.3-0.5

Recom R-78HB3.3-0.5 Switching Regulator is a through-hole DC-DC converter designed for industrial and electronic applications requiring stable low-voltage power supply. It accepts a wide input voltage range up to 72V DC and converts it to a constant 3.3V DC output with a maximum output current of 500mA. The SIP package and 3-terminal pin layout facilitate straightforward PCB mounting and wiring.

Equipped with integrated short-circuit protection, this regulator ensures reliable operation by preventing damage from power surges or fault conditions. Its efficient 76% power conversion minimizes heat dissipation, enhancing device longevity. The low ripple and noise specification (20mV peak-to-peak) is suitable for sensitive electronic circuits where stable power is critical.

Engineered to operate in harsh environments, this unit maintains performance across a wide temperature range from -40°C to +85°C, making it suitable for applications in telecommunications, automotive systems, domestic appliances, and communication/networking devices. Its compact dimensions of 11.5mm x 8.5mm x 17.5mm and lightweight 4g design contribute to low-profile installations without imposing mechanical strain on PCBs.

The high Mean Time Between Failure (MTBF) of approximately 7.4 million hours underscores the reliability expected from Recom products, delivering consistent performance in industrial and commercial settings.

Features a 3.3V DC output voltage with 0.5A current capacity. Compatible with input voltages ranging from 9V to 72V DC. Through-hole mounting design with 3 terminal pins for electrical connection. Compact SIP (Single Inline Package) form factor suitable for space-constrained PCBs.
