The F0512N-1WR3 is a 1W isolated DC-DC converter module from MORNSUN's F_N-1WR3 series, specifically designed for on-board power systems requiring a voltage isolated from the input power supply . This model operates with an input voltage range of 4.5V to 5.5V and provides a regulated 12V output with up to 84mA output current . Key features include continuous short-circuit protection, ultra-low no-load input current of 8mA, and 3000VDC isolation voltage with efficiency up to 85% . The module operates reliably over a wide temperature range of -40°C to +105°C and features international standard pinout in a compact DIP package measuring 12.70 x 10.16 x 8.20 mm . It is ideal for applications in pure digital circuits, general low-frequency analog circuits, relay drive circuits, data exchange circuits, and similar applications .
