What are the key specifications of the LQM21PN4R7MGRD?

It features a 4.7 µH inductance, ±20% tolerance, 0.23 Ω max DC resistance, and a 30 MHz minimum self-resonant frequency in an 0805 package.

What should engineers review before using this inductor?

Review the rated current derating curve, as the current capacity decreases significantly when operating between 85°C and 125°C.

What are the handling precautions for this component?

Avoid using magnetic tweezers, as magnetism can alter the inductance value. Also, ensure the PCB design minimizes mechanical stress to prevent cracking.

What should sourcing teams check before buying LQM21PN4R7MGRD?

Check lifecycle (Active), compliance data, distributor availability, and approved-source coverage. Current sourcing signal: Low; readiness: easy.

What is the pinout of LQM21PN4R7MGRD?

Use the LQM21PN4R7MGRD datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about LQM21PN4R7MGRD pinout to locate pins, power rails, and interface signals before layout.
