With a maximum DC resistance of 480 mOhm, the I²R loss at full rated current sits at roughly 43 mW — well within the 125 °C ambient ceiling for a 1210 footprint. ## Frequency ceiling and Q — where it works and where it doesn't The self-resonant frequency is 40 MHz, with a Q of 20 measured at 1 MHz. Below 40 MHz the component behaves as an inductor; above that the parasitic capacitance dominates and the impedance drops. This sets a practical upper switching-frequency limit around 10–15 MHz for a buck converter's inductor — beyond that the effective inductance collapses. Unshielded construction means the magnetic field radiates from the drum core. In a layout with sensitive analog or RF traces on the same layer, maintain a keep-out zone of at least one part width (3.2 mm) around the inductor to avoid coupled noise into the signal chain. ## 1210 footprint and PCB integration The ferrite core material handles the DC bias without saturating up to the rated 300 mA — derate the current above 85 °C per the Murata application note for the LQH32 series.","metaTitle":"Murata LQH32NH8R2J23L Inductor, 8.2 µH, 300 mA, AEC-Q200","metaDescription":"Murata LQH32NH8R2J23L drum core wirewound inductor, 8.2 µH, 300 mA, 480 mOhm DCR, AEC-Q200 qualified.
