56 µH shielded drum core for automotive power rails
The Coilcraft LPS6235-563MRC is a 56 µH shielded drum core inductor in the LPS6235 series, qualified to AEC-Q200 for automotive-grade reliability. Rated for 750 mA continuous current with a saturation current floor of 1 A, it suits DC-DC converter output filtering and EMI suppression in engine-bay or cabin electronics where the ambient temperature range is -40°C to 125°C.
Current handling and DC resistance — the thermal budget
The 280 mOhm max DCR sets the I²R conduction loss — at 750 mA the self-heating is roughly 158 mW, which the 2424 (6060 Metric) footprint dissipates without exceeding the ferrite core's Curie temperature. The 1 A saturation current (Isat) is the point where inductance drops by 10 % typical — a DC-DC converter drawing transient peaks above 750 mA should budget the inductance roll-off into the ripple current calculation.
Shielding and self-resonant frequency
Shielded construction contains the magnetic field within the 6.20 mm × 6.20 mm footprint, reducing radiated EMI into adjacent traces or nearby inductors in a multi-phase regulator layout. The self-resonant frequency of 12 MHz sits well above the 100 kHz test frequency — the inductor behaves as a pure inductance up to several MHz, making it usable in switching regulators switching at 500 kHz to 2 MHz.
Active production — no lifecycle risk for new designs
AEC-Q200 qualification means the part has passed the full automotive stress suite (thermal shock, vibration, moisture resistance, solder heat) and is PPAP-ready for Tier-1 submissions.
