Instructions for Use:

1. Mounting:

   • Ensure the PCB pad dimensions match the recommended footprint for the SFK-112DM.
   • Use reflow soldering with a peak temperature of 260掳C for no more than 10 seconds.

2. Handling:

   • Handle with care to avoid mechanical stress on the component.
   • Store in a dry environment to prevent moisture damage.

3. Testing:

   • Measure inductance using an LCR meter at 1 kHz.
   • Ensure the DC resistance is within the specified tolerance.

4. Operational Considerations:

   • Do not exceed the rated current to prevent overheating and potential failure.
   • For optimal performance, ensure the operating temperature remains within the specified range.

5. Soldering Profile:

   • Preheat the PCB to 100掳C to 120掳C.
   • Apply solder paste to the pads.
   • Place the component on the pads and reflow solder according to the recommended profile.

6. Storage:

   • Store in a cool, dry place away from direct sunlight and sources of heat.
   • Use within 6 months of receipt for best performance.
