RECOM DC-DC Converter, ±15 % Load Regulation, 1000μF Maximum Capacitative Load - ROM Series - ROM-0505S
This DC-DC converter from RECOM proves that big things come in small packages. Mount it on a PCB in systems where space is at a premium. Thanks to dimensions of 6.05 (W) x 11.5 (L) x 7.7mm (H), it's a breeze to fit into devices like phones or sensitive medical equipment. As the input and output voltages are the same, you can use this unit to isolate your circuit board from the power source to protect it from short-circuiting. Rest assured, with a 78% efficiency rating, most of that electricity gets converted and not much is wasted as heat.
• Wide operating temperature range of -40°C to +85°C for use in demanding applications
• Light 1g weight won't put unnecessary strain on a PCB
• Short-circuit protection safeguards attached devices from overload
