RECOM Switching Regulator, 97% Maximum Efficiency, 40mV Maximum Ripple Voltage - R-78AA-0.5 Series - R-78AA12-0.5SMD
Flick over to fast power conversion with this RECOM switching regulator. It's a middleman that takes high inputs between 15 and 32V DC and delivers a steady 12V DC output to keep your components working smoothly. A start-up time of just 50ms means it switches your input voltages in a flash to efficiently power attached appliances. Integrated short-circuit protection automatically resets the unit after tripping to help your system bounce back from electrical faults. Don't worry about making space for a heatsink, as the regulator's 97% conversion efficiency keeps your equipment running cool.
• Surface mounting method for quick installation
• Compact dimensions of 15.3 (L) x 9.6 (W) x 8.8mm (D) mean it's easy to mount in crowded spaces
• Low power dissipation of 0.4W, so you get energy-efficient voltage conversion
• 33 units in a tube for convenient stocking
