Specifications
Parameter Guide
Understand the key electrical and mechanical specifications for MILS1812-224K.
MILS1812-224K has an inductance value of 220 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.
MILS1812-224K is rated for 149 mA. Current rating helps determine whether the part can carry the expected DC or RMS current without excessive heating or saturation risk.
MILS1812-224K lists a DC resistance of 9Ohm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
MILS1812-224K uses a package or case of Nonstandard. Package size affects PCB footprint, height clearance, thermal behavior, and compatibility with automated assembly.
