6.8 µH shielded wirewound for DC-DC filtering
The Murata LQH32PB6R8NNCL is a shielded drum-core wirewound inductor in the LQH32 series, rated 6.8 µH ±30% at 1 MHz test frequency. Its 550 mA continuous current rating and 1.3 A saturation current define the usable load range — the inductor stays within its linear inductance region up to 1.3 A, beyond which the ferrite core saturates and inductance drops sharply. Shielding contains the magnetic field, reducing EMI coupling into nearby traces or components — a practical advantage when the inductor sits next to a sensitive ADC input or a clock line on the same board layer.
DC resistance and thermal budget
Maximum DC resistance is 264 mOhm. At 550 mA, I²R loss is about 80 mW — negligible in most designs, but worth checking if the inductor is in a high-density board with limited airflow. The ferrite core material handles -40°C to +125°C operation, covering automotive under-hood and industrial enclosure ambient. Self-resonant frequency is 40 MHz. Above that, the inductor behaves capacitively — the 6.8 µH value holds up to roughly 40 MHz, making it a fit for switching regulators switching in the hundreds-of-kHz to low-MHz range.
1210 footprint and rework reality
The 1210 footprint is common enough that a standard hot-air rework station can swap it on a populated board without a dedicated nozzle. Orientation is unambiguous: the part is symmetrical, but the pad layout on the board determines polarity for the magnetic field direction, so note the silkscreen dot if the layout uses one.
