Shielded drum core, 4.7 mH, AEC-Q200
The Coilcraft LPS6235-475MRC is a shielded drum core inductor in the LPS6235 series, wound on a ferrite core and housed in a 2424 (6060 Metric) surface-mount package. Inductance is 4.7 mH at 100 kHz test frequency, with ±20% tolerance. Rated for 110 mA continuous current, with a saturation current floor of 70 mA — the point at which inductance drops by the specified percentage. Maximum DC resistance is 14.5 Ω, which sets the I²R loss at full rated current to about 175 mW, well within the package's thermal budget for most board layouts. Self-resonant frequency is 940 kHz. Above this frequency the component behaves capacitively, so the inductor is best applied in DC-DC converter output filters or EMI suppression circuits where the switching fundamental stays below 940 kHz.
AEC-Q200 qualification and temperature range
Rated AEC-Q200, the automotive-grade passive component stress test qualification. This means the part has passed the full suite of reliability tests — thermal shock, humidity bias, mechanical shock, vibration, and solder heat resistance — per the AEC-Q200 rev D or later standard. Operating temperature range is -40°C to +125°C, covering the under-hood and passenger-cabin ambient profiles for most automotive ECUs. The shielded construction contains the magnetic field within the core, reducing radiated EMI into adjacent circuitry — a requirement for noise-sensitive automotive sensor interfaces and CAN/FlexRay transceiver supply rails.
The ferrite core and shielded construction mean the component has no exposed magnetic path — standard pick-and-place handling applies, with no special keep-out zones for adjacent magnetic sensors.
