68 µH shielded inductor with AEC-Q200 grade
The Coilcraft LPS6235-683MRC is a 68 µH shielded drum-core inductor in the LPS6235 series, rated for 730 mA continuous current with a maximum DCR of 345 mOhm. The shielded ferrite core contains the magnetic field, reducing radiated EMI to adjacent traces and components in a dense PCB layout — a practical advantage when routing power rails near sensitive analog or RF sections.
Current, DCR, and saturation limits
The 730 mA current rating is the DC current at which the temperature rise stays within the part's self-heating limit given the 345 mOhm DCR — at full rated current, I²R loss is about 184 mW, which the 2424 package dissipates without exceeding the 125°C ceiling. Saturation current is 900 mA, 23% above the rated current — this headroom means the inductance holds within tolerance during transient load steps up to that level, important for buck converter output stages where peak inductor current exceeds the DC average. Self-resonant frequency is 10.8 MHz — above this frequency the inductor's parasitic capacitance dominates and the component behaves capacitively, so the useful filtering range stops well below 10 MHz.
Temperature range and package fit
Inductance is tested at 100 kHz, the standard frequency for power inductor characterization — the ±20% tolerance is typical for shielded ferrite-core inductors in this value range.
