The Panasonic surface-mount power inductor ETQPAMR68JFW is an automotive-grade component with notable features, as follows:
It has an inductance of 0.68µH with a tolerance of ±15%, and the DC resistance at 20°C is typically 0.70mΩ, with a maximum of 0.77mΩ.
The size of the inductor is 17.2×15.6×10.5mm, which is relatively compact and can meet the space-saving requirements of automotive electronic control units and other applications.
Its rated current is 65A under the condition that the overall temperature rise is 40K when installed on a high-heat-dissipation multi-layer substrate, and the saturation current is 53A.
The guaranteed operating temperature range is -40°C to +160°C, including its own temperature rise. It can also be used briefly at temperatures below 180°C.
The inductor has good vibration resistance with an amplitude of less than 5mm, a scanning speed of 1 oct/min, a frequency of 5-2000Hz, 2 hours in each of the three directions (total of 6 hours), and a vibration resistance of 71G.
Made of metal-magnetic materials, silicone resin, and coil windings. The integrated-molding structure formed by the metal-composite magnetic core has no gaps, low leakage flux, which reduces noise interference and benefits high-density layouts.
It complies with the AEC-Q200 standard for automotive applications and also meets the requirements of the RoHS directive, providing high reliability and environmental friendliness.
