RECOM DC-DC Converter, ±5% Output Voltage Accuracy, 75% Efficiency Rating - RE Series - RE-123.3S

Smooth out your power supply with this RECOM DC-DC converter. It switches a 12V input load to a 3.3V output, so it's a handy way to adjust your electrical source to suit low-voltage components. The device has a 75% conversion efficiency so it saves energy and keeps costs down. Simple through-hole mounting means you can quickly make secure connections to a circuit board. By handling high voltages up to 1kV, this converter can deal with sudden power surges, cutting the risk of machine damage.

Features & Benefits

• Line regulation of ±1.2% keeps output voltages stable for a reliable power supply

• Compact measurements of 19.6 (L) x 6 (W) x 10.2mm (H) mean it fits easily onto a busy PCB

• Handles operating temperatures between -40°C and +85°C, so it's suited to tough industrial settings

Applications

• Mobile phone chargers

• Renewable energy installations

• Automotive industry

How do I identify the pins on this converter?

The front of the unit has a large dot label to help you line it up with the diagram in the instructions, making it easy to identify the pins.
