Looks great just wrong size for me

### ⭐⭐⭐⭐⭐ nice coils
*by B***R on October 16, 2025*

These inductors are good quality and my LCR meter confirms the specs. Happy with the price and the quality and I am excited to finally build my first voltage boost poc for a solar panel project I have been thinking about for a year. Its taken me a year to prepare my skills to apply this inductor but im there now and cannot wait to see these puppies work for real.
