Instructions for Use:

1. Handling:

   • Handle the 3590S-2-202L with care to avoid damage to the terminals and body.
   • Use appropriate ESD (Electrostatic Discharge) protection measures.

2. Mounting:

   • Place the inductor on the PCB according to the specified footprint.
   • Ensure that the solder pads are clean and free from contaminants.
   • Apply a small amount of solder paste to the pads.
   • Use a reflow soldering process with a recommended profile:
     • Preheat: 120°C to 150°C for 60 to 120 seconds
     • Soak: 150°C to 180°C for 60 to 120 seconds
     • Reflow: 210°C to 230°C for 10 to 20 seconds
     • Cooling: 5°C to 10°C per second

3. Storage:

   • Store the inductors in a dry, cool place away from direct sunlight and moisture.
   • Use within the recommended shelf life to ensure optimal performance.

4. Testing:

   • Verify the inductance and DC resistance using a suitable LCR meter.
   • Ensure that the inductor meets the specified tolerance and electrical characteristics.

5. Applications:

   • Suitable for use in power supply circuits, DC-DC converters, and filtering applications.
   • Ideal for high-frequency switching applications due to its low DC resistance and high current rating.

6. Safety:

   • Ensure that the inductor is used within its rated current and temperature range to avoid overheating and potential failure.
   • Follow all relevant safety guidelines and regulations when handling and installing the inductor.
