For full control of power delivery to your PCB-linked devices, go for this small-but-mighty DC-DC converter from Traco Power. It packs a 5W power rating into compact dimensions of 13.2 (L) x 9.1 (W) x 10.2mm (D), so takes up minimal space. The unit steps down input signals ranging between 18 and 75V to a stable 5V output that's useful for components like LED lights and sensors. For extra safety, it puts an isolation barrier of 1.6kV between the supply and the output to make sure you aren't caught unawares by sudden power spikes.

• Suitable for use in challenging settings, thanks to an operating temperature range between -40°C and +75°C
• Mean time between failures of over 2.2 million hours for reliable long-term performance
• Non-conducting FR4 casing for durability and insulation to ensure safe operation and risk-free handling

• Military equipment
• Plant automation
• Robotics and automation systems

Yes, this unit resists up to ±8kV of ESD in the air and ±6kV of contact discharge, making it useful for use in volatile systems.
