SMD Inductor LQM18DN100M70L

What is LQM18DN100M70L?

The LQM18DN100M70L is a fixed SMD inductor from muRata (村田). Its core parameters are 10 µH inductance, 300 mA rated current, and a DCR of 1.365 Ω. RoHS compliant, this component delivers stable filtering and energy storage in space-constrained DC-DC circuits.

✔ RoHS Compliant  /  ✔ SMD  /  ✔ muRata Quality  /  ✔ Long-Term Supply

Typical Applications & Why This Part Fits

• Portable Power Management: With 10 µH inductance and 300 mA rating, this inductor efficiently smooths ripple in battery-powered buck converters for wearables and IoT modules.
• Low-Noise RF Supply Rails: The 1.365 Ω DCR minimizes resistive loss while the 10 µH value attenuates high-frequency noise on sensor or wireless chip power lines.
• LED Driver Circuits: Reliable 300 mA current handling and compact SMD footprint allow integration into constant-current LED drivers for indicator lights and small displays.

Key Features & Advantages

• Precision 10 µH Inductance: Tight tolerance ensures consistent filtering performance across production batches.
• Low 1.365 Ω DCR: Reduced copper losses improve converter efficiency in low-power designs.
• 300 mA Saturation Current: Handles transient peaks without significant inductance drop, enhancing circuit stability.
