The 100 mA current rating is the DC bias limit — push past it and the inductance rolls off as the core saturates, turning your filter into a low-value choke. The 4.3 Ohm max DCR means at 100 mA you lose 430 mW to self-heating; for a power rail filter that heat adds to the board thermal budget, so check the derating if ambient runs near the 85°C ceiling. The 11 MHz self-resonant frequency sets the upper limit for inductive behaviour — above 11 MHz the part looks capacitive. In a 1 MHz buck converter output filter the margin is comfortable; in a 10 MHz switching regulator you are operating near SRF and the effective inductance is already dropping. The unshielded construction means the magnetic field radiates — keep this inductor at least a few millimetres from sensitive analog or RF traces, or plan a shielded alternative if crosstalk shows up in the first prototype.","metaTitle":"Murata LQH32MN470K23L 47 µH Unshielded Inductor, 100 mA","metaDescription":"Murata LQH32MN470K23L drum core wirewound inductor, 47 µH ±10%, 100 mA, 4.3 Ohm DCR, unshielded, 1210 package.
