Rated for 1.4 A continuous current with a saturation floor of 1.2 A, it carries a maximum DC resistance of 117.6 mOhm — a combination that keeps conduction losses manageable in a 4.50 x 3.20 mm footprint. The AEC-Q200 qualification (Grade 3, -40°C to +85°C) means this part is screened for automotive-grade thermal cycling, vibration, and bias humidity — it belongs on a power rail in an ECU, sensor module, or infotainment board where the ambient stays inside the industrial band. ## Current rating and saturation margin The 1.4 A continuous current rating is the thermal limit at 85°C ambient — the wire temperature rise stays within the ferrite core's Curie margin at that load. Saturation current is specified at 1.2 A, about 14% below the continuous rating, which is typical for a shielded drum-core construction where the magnetic path saturates before the winding overheats. For a buck converter switching at 1 MHz (the test frequency), the 6.8 µH value and 1.2 A Isat give enough energy storage to smooth ripple current in a 12 V to 3.3 V rail at moderate loads. ## Shielding and self-resonant behaviour The shield reduces magnetic flux leakage into adjacent traces and components — important when the inductor sits next to a sensitive analog front-end or a wireless transceiver on the same board. Self-resonant frequency is 30 MHz, well above the 1 MHz test frequency, so the inductor behaves as a pure inductive element in typical switching regulator loops below 10 MHz.","metaTitle":"Murata LQH43PH6R8M26L Shielded Power Inductor, 6.8 µH, 1.4 A","metaDescription":"Murata LQH43PH6R8M26L shielded wirewound inductor, 6.8 µH ±20%, 1.4 A, 117.6 mOhm DCR.
