Product Description
Recom R-78W3.3-0.5 DC/DC Switching Regulator is a high-performance power supply solution designed for demanding electronic applications. This through hole mount regulator delivers a stable 3.3V DC output voltage at a current of 500mA, with a rated power of 16W, making it ideal for low-voltage device operation.
Featuring a compact SIP-3 package measuring 17.5mm in width and depth and 11.5mm length, this regulator is well-suited for space-constrained installations. It operates efficiently within a broad input voltage range of 6.5V to 32V DC, and can function reliably in extreme temperature environments from -40°C up to 85°C without derating.
With a high efficiency of 88%, the unit minimizes power loss and limited heat dissipation, removing the need for additional heatsinks. Low ripple and noise levels (75mV peak-to-peak) ensure clean power delivery, essential for sensitive electronics. Precise voltage regulation is maintained through ±0.4% line regulation and ±0.6% load regulation parameters.
Built-in short circuit protection with an automatic recovery mechanism protects the device and connected circuitry from electrical faults, enhancing operational safety and reliability. The device also includes diode protection circuitry and supports a maximum capacitive load of 220μF.
This switching regulator's exceptionally long mean time between failures (MTBF) of approximately 9,368,000 hours attests to its durability and suitability for industrial, automotive, test and measurement instrumentation, process machinery, and packaging equipment applications.
Manufactured in Taiwan, the product complies with multiple international standards including UL, CE, REACH, IEC 60950-1 (2nd and 3rd editions), and RoHS, ensuring compliance with quality and environmental regulations.
High efficiency up to 88% to reduce energy losses. Wide operating temperature range from -40°C to 85°C. Low output ripple and noise supporting signal integrity. Robust short circuit protection with automatic recovery. Compact SIP-3 through hole package for easy PCB integration.
Long MTBF exceeding nine million hours for dependable operation. Suitable for industrial, automotive, and instrumentation applications. Compliance with international safety and environmental standards.
