LQM18PN2R2MFRL is the 2.2 µH ±20% member of Murata's LQM18PN_FR chip-coil series for general electronic equipment: a 0603 body (1.6 × 0.8 × 0.8 mm) with its inductance specified at 1 MHz.p.1, p.2 It carries 0.30 Ω ±25% of DC resistance and a 750 mA rated current, with self-resonance above 70 MHz.p.1
The 750 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
