RECOM DC-DC Converter, 1 Output, 500V AC Isolation Voltage - RM Series - RM-1212S
This DC-DC converter from RECOM is your new best friend when it comes to power management. It takes an input voltage between 10.8 and 13.2V DC and adjusts it to a safe 12V DC output to drive connected devices. Built-in short circuit protection is on hand to protect this unit from hazards like current surges. It has a broad operating temperature range between -40°C and +85°C so you can rest assured it can handle the heat in harsh conditions. Fitting this unit onto a busy board is a cinch, as its compact dimensions of 11.5 (L) x 10mm (D) mean it takes up little space.
