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 LQH3NPN_MR series?
9. The table above lists every one, sorted by part number.
What do the parts in the LQH3NPN_MR 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 LQH3NPN_MR part?
Each part number links to Murata's official product page, which carries the detailed specification sheet, reliability data and simulation models.
