    Selection Notes

    • Rated current is quoted against two different criteria — inductance drop and temperature rise. The usable current is the lower of the two for your application.
    • DC resistance sets the copper loss. In high-current paths the DCR term can dominate the total loss budget, so compare DCR before inductance tolerance.
    • Shielded construction keeps the field inside the package. Unshielded parts are smaller and cheaper but radiate into neighbouring traces.
    • Saturation behaviour is soft in metal-alloy parts and sharp in ferrite. Choose according to whether the fault current must be limited or simply ridden through.

    Common Questions

    How many part numbers are in the LQM21NN_10 series?

    21. The table above lists every one, sorted by part number.

    What do the parts in the LQM21NN_10 series have in common?

    They share the same inductor construction and case-size family; the differences are the electrical values shown per row.

    Where can I find the full specification for a LQM21NN_10 part?

    Each part number links to Murata's official product page, which carries the detailed specification sheet, reliability data and simulation models.
