What Is the Difference Between Murata LQH3NPN100MMEL and LQH3NPN100MEEL?
The primary difference lies in the height profile and current rating specifications within the LQH3NPN family. While both share the same 3.0 x 3.0 mm footprint and 10 uH inductance, the "MMEL" suffix designates a specific maximum height (1.4 mm) and optimized DC resistance/saturation current balance compared to other suffix variations in the series. Always verify the exact thickness limit and DCR requirements in your PCB layout specifications.
