At the rated current, the 390 mOhm max DCR produces an I²R loss of roughly 79 mW — a figure that stays within the 105°C operating limit when the ambient is below 85°C and the board has moderate copper pour. ## AEC-Q200 qualification and deployment envelope The unshielded drum-core construction radiates the magnetic field — the layout must keep sensitive analog traces, low-level sensor lines, or RF signal paths at least 3 mm from the inductor body to avoid coupling. For a DC-DC converter input filter, the radiated field is usually not a concern; for a precision ADC reference filter, it is. ## Self-resonant frequency and frequency-domain fit The 26 MHz self-resonant frequency (SRF) marks the point where the inductor's parasitic capacitance cancels the inductance — above 26 MHz the component behaves capacitively and no longer provides inductive impedance. For a buck converter switching at 2 MHz, the SRF is well above the fundamental and the first few harmonics, so the inductor filters effectively. For a 10 MHz switching regulator or a filter above 10 MHz, the margin narrows and the effective inductance rolls off. Inductance is tested at 1 MHz, which is the standard test frequency for the 10 µH value in the 1210 package. The ±10% tolerance band covers the full operating temperature range and DC bias condition up to the rated current. ## Package and reflow integration The ferrite core and wirewound construction are compatible with standard lead-free reflow profiles (peak 260°C, 30 seconds above 255°C).","metaTitle":"Murata LQH32DZ100K53L 10 µH Inductor, 450 mA, AEC-Q200","metaDescription":"Active-production Murata LQH32DZ100K53L drum-core wirewound inductor, 10 µH ±10%, 450 mA, 390 mOhm DCR, AEC-Q200. 1210 SMD.
