R05CT05S
5W isolated DC-DC converter with 4.5-9V input and regulated 5V output in compact SIP package.
Product Overview
Description
The R05CT05S from Recom is a high-reliability 5W isolated DC-DC converter designed for demanding industrial applications. Featuring a 2:1 input voltage range of 4.5-9VDC, this converter accepts nominal 5V or 6V inputs commonly found in distributed power systems and battery applications. The regulated 5VDC output provides stable power for sensitive electronics, while the 1000VDC isolation voltage ensures safety and noise immunity. The compact SIP-7 package (19.5 x 7.5 x 10.2mm) enables high-density PCB designs without sacrificing thermal performance. With efficiency up to 85%, the R05CT05S minimizes heat generation, reducing cooling requirements and improving system reliability. The converter includes built-in protection against short circuits, overcurrent, and overtemperature conditions. Operating temperature range of -40°C to +85°C without derating makes it suitable for harsh industrial environments. The R05CT05S meets UL/EN/IEC 62368-1 safety standards and is RoHS compliant. Its MTBF exceeds 2 million hours at 25°C, ensuring long-term reliability in critical applications.

Frequently Asked Questions
What is the minimum input voltage for the R05CT05S?
The minimum input voltage is 4.5VDC. Below this voltage, the converter may not start or maintain regulation. For reliable operation, maintain input voltage above 4.5VDC under all load conditions. For detailed specifications and application support on recom R05CT05S, refer to the datasheet or contact our team.
Ensure your power source maintains >4.5VDC under worst-case conditions (maximum load, low battery, etc.).
Can the R05CT05S operate at full load at 85°C ambient?
Yes, the R05CT05S is rated for full 5W output from -40°C to +85°C ambient without derating. However, at high ambient temperatures, ensure adequate airflow or heat sinking to keep the case temperature within limits.
For high-temperature applications, verify thermal design with actual operating conditions and provide adequate cooling.
What external components are required?
The R05CT05S requires minimal external components: Input capacitor: 10μF ceramic recommended for stability; Output capacitor: 10μF ceramic for ripple reduction; Optional input filter for conducted EMI if required by application. No external inductors, diodes, or feedback components needed.
Use quality ceramic capacitors with adequate voltage rating. Place capacitors close to converter pins for best performance.
