LQM21PN_G0 Murata Multilayer type Inductor 2012

The Murata LQM21PN_G0 series covers 4 part numbers across case sizes 2012. All parts in the series share the same construction and qualification, and differ in the values listed in the table below — so a design can move up or down the range without changing footprint.

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 LQM21PN_G0 series?

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

What do the parts in the LQM21PN_G0 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 LQM21PN_G0 part?

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