F1209s-1wr3 DC DC Converter 12V to 9V 1W is designed to convert a constant voltage input to an isolated non-stabilized voltage single output of 1W. With a transfer efficiency of 88% (Typical), this converter provides high efficiency for its users. The converter requires isolation between input and output, with an isolation voltage of ≤1500VDC. It also includes output short-circuit protection to ensure safety. The voltage of the input power supply must be relatively stable, with a voltage variation range of ±10%Vin. The operating temperature range is -40°C~+85°C, and the output voltage stability is not required.

The F1209s-1wr3 DC DC Converter 12V to 9V 1W comes in a small SIP package with international standard pins, making it easy to install directly onto a PCB board. Additionally, it adopts high-quality environmental protection, waterproof, and heat-conducting adhesive for filling and sealing, ensuring moisture-proof and vibration-proof operations that meet the waterproof and dustproof IP65 standard. With a high-reliability and long-life design, the converter can work continuously for a long time, with a Mean Time Between Failures (MTBF) of ≥3.5 million hours (3500000Hrs).
