The 450 mA rating is the DC current at which the inductance typically drops by 10 % due to core saturation — above that, the inductance rolls off, and the ripple current in a buck converter rises. The 390 mOhm DCR sets the I²R loss at full current to about 79 mW, which is well within the 105 °C temperature ceiling of the ferrite core. The self-resonant frequency is 26 MHz, measured at 1 MHz test frequency. For a 10 µH inductor, that SRF is typical of a ferrite-core wirewound in the 1210 package — above 26 MHz the part behaves capacitively, so it should not be used as a filter element near or above that frequency. The unshielded construction means the magnetic field extends outside the body; keep a clearance of at least one part width from adjacent traces carrying sensitive analog signals. ## 1210 footprint and board integration The nonstandard package designation means the pad layout follows the 1210 land pattern per IPC-7351B — no special thermal pad or via array is needed. Surface-mount reflow profile follows the standard lead-free profile for ferrite components; the ferrite core is not moisture-sensitive, so no bake is required before reflow.","metaTitle":"Murata LQH32DN100K53L 10 µH Unshielded Inductor, 450 mA","metaDescription":"Murata LQH32DN100K53L drum-core wirewound inductor, 10 µH ±10%, 450 mA, 390 mOhm DCR, 1210 footprint.
