Specifications
Parameter Guide
Understand the key electrical and mechanical specifications for M1331-122K.
M1331-122K has an inductance value of 1.2 µH. This value indicates how much magnetic energy the component can store and is one of the first parameters to compare when selecting an inductor.
M1331-122K is rated for 247 mA. Current rating helps determine whether the part can carry the expected DC or RMS current without excessive heating or saturation risk.
M1331-122K lists a DC resistance of 730mOhm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
M1331-122K uses a package or case of Nonstandard. Package size affects PCB footprint, height clearance, thermal behavior, and compatibility with automated assembly.
