TRACOPOWER Switching Regulator, Through Hole, ±12V dc Output Voltage, 13.5 → 24 V dc, 13.5 → 42 V dc

Get your equipment up and running with this switching regulator from Traco Power. It's a step-down converter that changes an input current of between 13.5 and 42V DC into a 12V DC output. This assembly offers ±0.2% line regulation and ±0.4% load regulation to keep performance on the straight and narrow. You can rest assured that it's built to last, thanks to a high mean time between failures of six million hours. Its through-hole mounting style is ideal in high-vibration environments as it achieves an unshakeable and permanent bond.

• Compact dimensions of 11.7 (L) x 7.5 (W) x 10.2mm (D) make it a space-saving option
• Reliable performance in temperatures between -40°C and +85°C suits use in harsh industrial conditions
• Up to 95% efficiency indicates minimal waste during conversion

• Medical equipment
• Communication and IT networks
• Building automation

No. There's no need for a heat sink with this regulator. Due to its high efficiency, it doesn't produce excess thermal energy and is cooled by free air.
