The Traco Power TDR 3-1212SM is a member of the TDR 3 series of compact 3W isolated DC DC converters. It provides a single regulated 12V output at 250mA from a 9-18V input range (2:1). The converter features 1600V DC input-to-output isolation, making it suitable for applications requiring galvanic isolation. It includes remote On/Off control and continuous short-circuit protection. The efficiency is typically 82%.
The TDR 3-1212SM is housed in a compact through-hole package with dimensions 18.9mm x 12.8mm x 8.7mm. It operates over a wide temperature range of -40°C to 85°C with derating. The converter is designed for ITE (commercial) applications and is fully RoHS compliant. It meets IEC 62368-1 and UL 62368-1 safety standards.
Typical applications include communication equipment, instrumentation, and industrial electronics where space is critical. The fully regulated output ensures stable performance even under no-load conditions. The low ripple and noise characteristics make it suitable for sensitive circuits.
