Instructions:

1. Installation:

   • Ensure the PCB layout is designed to accommodate the dimensions of the RJH60F7ADPK.
   • Use a soldering iron with a temperature setting suitable for surface mount components.
   • Apply a small amount of solder paste to the pads on the PCB.
   • Place the transformer on the PCB, ensuring it is aligned correctly.
   • Solder the transformer to the PCB, starting from the center and moving outward to avoid thermal stress.

2. Operation:

   • Connect the input voltage (12 VDC) to the designated input pins.
   • Connect the load to the output pins, ensuring the current does not exceed 3 A.
   • Monitor the temperature of the transformer during operation to ensure it stays within the operating temperature range (-40°C to +85°C).

3. Testing:

   • Measure the output voltage to ensure it is stable at 5 VDC.
   • Check the efficiency by measuring the input and output power and calculating the ratio.
   • Perform an insulation test using a megohmmeter to verify the insulation voltage (3000 VAC for 1 minute).

4. Storage:

   • Store the transformer in a dry, cool place within the storage temperature range (-55°C to +125°C).
   • Avoid exposure to high humidity and corrosive environments.

5. Safety:

   • Always handle the transformer with care to avoid physical damage.
   • Ensure proper grounding and isolation when working with high voltages.
   • Follow all relevant safety guidelines and regulations for handling electronic components.
