TRACOPOWER TMR 3WI DC-DC Converter, 12V dc/ 250mA Output, 18 → 75 V dc Input, 3W, Through Hole, +85°C Max Temp

Adapt your power source to suit your kit with this Traco Power DC-DC converter. It takes an input voltage of 18 to 75V DC and down-steps it to a steady 12V DC output. The unit has an 81% conversion efficiency, which minimises the need for an additional cooling mechanism as its heat output is low. Slotting the unit onto a PCB is no problem, thanks to its compact SIP8 footprint. Continuous short-circuit protection is on hand to ensure safe operation and prevent damage to downstream equipment.

• Remote ON/OFF function provides hassle-free appliance control
• Maximum ripple voltage of just 30mVp-p minimises disruption from power line noise
• Through-hole mounting for quick and easy fixing to a board
• Plastic and silicone insulation provide protection against electrical faults
• 820μF capacitive load ensures a smoother output voltage and reduced voltage ripple

• Manufacturing industry
• Charging stations
• Portable devices

Yes, this converter performs reliably in temperatures between -40°C and +85°C, so it's a safe bet for challenging workplaces.
