The 620 mA continuous current rating is the DC current the part carries before the inductance drop exceeds the application's margin — the DCR of 176.4 mOhm max sets the copper loss at that current: 0.62² × 0.1764 ≈ 68 mW of self-heating, well within the 125°C ceiling. ## Saturation headroom and self-resonant ceiling The 1.05 A saturation current (Isat) is the point where the ferrite core starts to saturate and inductance drops — 70% headroom above the 620 mA rated current means the inductor holds its value through load transients in a buck converter without the current loop going unstable. The 20 MHz self-resonant frequency (SRF) is the point where the inductor's parasitic capacitance cancels the inductance; above SRF the part behaves capacitively, so keep the switching frequency well below 20 MHz — typically 1–2 MHz for a power inductor of this value. ## Shielded construction and board footprint The ferrite shield keeps the magnetic field contained — no crosstalk into adjacent traces or other inductors in a densely packed 1812 footprint. The 4.50 mm × 3.20 mm body with 2.80 mm seated height fits the standard 1812 (4532 Metric) land pattern; the surface-mount reflow profile follows the standard lead-free solder curve for a ferrite-core part. ## Active production — sourcing posture No pin-compatible second-source is listed, but the 1812 shielded footprint is a common form factor — a parametric search for 10 µH, 620 mA, 1812 yields several drop-in candidates if a hedge is needed.","metaTitle":"Murata LQH43PB100M26L 10 µH Shielded Inductor, 620 mA","metaDescription":"Active-production Murata LQH43PB100M26L drum-core wirewound inductor, 10 µH ±20%, 620 mA, 176.4 mOhm DCR, shielded 1812 package.
