Product Description
Recom R-78W12-0.5 is a high-performance switching regulator designed for efficient power management in electronic devices requiring a stable 12V DC output and up to 500mA current. The compact SIP-3 through-hole package measures 11.5mm in length, 10.2mm in width, and has a depth of 10.2mm, making it ideal for installation in compact assemblies where space is limited.
This switching regulator achieves up to 97% efficiency, significantly reducing heat dissipation and eliminating the need for additional heatsinks or cooling fans. Its non-conductive plastic housing enhances electrical safety and protects against shocks.
Reliable operation over a wide temperature range from -40°C to 85°C ensures suitability for demanding industrial, medical, and electrical transmission environments. The regulator features line regulation of 0.2% and load regulation of 0.4%, ensuring consistent voltage supply under varying load and input conditions. Ripple and noise are maintained low at 35mV peak-to-peak, contributing to the stability of connected circuits.
The device supports inputs from 15V up to 32V DC and includes a built-in diode protection circuit to prevent reverse feedback, preserving long-term reliability and reducing risks of damage. Its mean time between failures (MTBF) is estimated at over 21 million hours, evidencing robust durability.
Typical applications include powering industrial cooling systems, medical equipment, and electrical transmission and distribution facilities where compact, efficient, and reliable switching regulators are essential.
