10 µH Inductor 0603 - Murata LQM18DH100M70L

Murata LQM18DH100M70L: 0603 AEC-Q200 Chip Inductor, 10 µH ±20%, 100 mA (ΔL) / 300 mA (temp rise). An Adom Basic Part: Adom keeps it on reels for its pick-and-place line, so boards built with it draw on Adom stock.

Key specs

Notes for designers

LQM18DH100M70L is the automotive one: a 10 µH ±20% chip coil from Murata's LQM18DH series, written against AEC-Q200 for powertrain and safety equipment and rated for −55 to +150 °C, operating and storage alike. (p.1, p.3) Inductance is measured at 1 MHz; (p.2) DC resistance is 1.05 ± 0.32 Ω and self-resonance sits above 32 MHz. (p.1)

Read the rated-current cell carefully, because it is the trap. The temperature-rise column allows 300 mA at 125 °C ambient, but the inductance-change rating is only 100 mA, beyond that the spec permits inductance to move as far as ±50% of its initial value. (p.1, p.2) A filter that must stay 10 µH designs to 100 mA, not 300. And at the top of the range the thermal budget nearly vanishes: the rating derates between 125 and 150 °C ambient down to 10 mA. (p.1)

The rest is undemanding: no marking, no polarity, (p.2) ESD withstand in the 6-8 kV rank, (p.1) and 4,000 pieces per reel on 8 mm plastic tape. (p.4)

Footprint

Redrawn from the datasheet land pattern (the previous pads were off by up to 0.5 mm).

Source: Land pattern from Murata reference specification JELF243B-9127G-01, p.7 (Land dimensions (reflow)).

Chip outline

The part's 3D outline in the standard pose (pad 1 toward the viewer), drawn from the STEP by Adom's OpenCascade service; the part number sits where the laser-etched mark is on the 3D model and reads the same way.

Symbol options

The default symbol, LQM18DH100M70L.kicad_sym (the one in the Symbol & Footprint panel), is the plain standard symbol. LQM18DH100M70L-outline.kicad_sym is the same symbol with the part's 3D chip outline drawn beside it, its part number placed and reading as on the 3D model.
