LQM18PN4R7MFRL is the largest FR value Adom stocks: 4.7 µH ±20% in the same 0603 body (1.6 × 0.8 × 0.8 mm) as the rest of Murata's LQM18PN_FR chip-coil series, inductance specified at 1 MHz.p.1, p.2 It trades current handling for inductance: 0.44 Ω ±25% of DC resistance, 620 mA rated, and self-resonance above 40 MHz — the lowest SRF of the series' seven values.p.1
The 620 mA is a thermal rating — 40 °C self-heating max — and the only rated-current criterion this spec defines, with no separate inductance-change figure.p.1, p.2 Operating range is −40 to +85 °C (storage −55/+125 °C),p.1 the body carries no marking,p.2 and the reel holds 4,000 pieces on 8 mm embossed plastic tape.p.4
