Power inductor for automotive DC-DC stages
The Coilcraft LPS6235-155MRC is a shielded drum core inductor in the LPS6235 series, built for DC-DC converter output filtering and EMI suppression in automotive power trains. Its 1.5 mH inductance at 100 kHz test frequency suits it for low-frequency ripple filtering in buck or boost stages where the switching frequency stays below the 1.9 MHz self-resonant point. Rated at 190 mA continuous current with a 4.6 Ohm max DCR, the I²R loss at full load is about 166 mW — the ferrite core and 2424 body dissipate that without exceeding the 125°C upper operating limit in still air. The saturation current of 120 mA is the hard ceiling: above that the inductance rolls off, so the design must keep peak transient current below that figure.
AEC-Q200 and the reflow profile
AEC-Q200 qualification means the part passed automotive-grade passive component stress tests: thermal shock, moisture resistance, mechanical shock, and vibration. For the EMS line, that translates to a known MSL (Moisture Sensitivity Level) — typically Level 1 for these ferrite drum cores — so it survives a standard 260°C peak reflow without pre-bake, provided the floor life hasn't been exceeded. The footprint is a standard two-terminal land pattern; the shielded ferrite body keeps flux from coupling into adjacent traces or components on a dense automotive PCB.
Active production and sourcing posture
Sourced through independent distribution channels. The part carries no known second-source cross-reference; the LPS6235 series footprint is unique to Coilcraft.
