Parameter Guide
Understand the key electrical and mechanical specifications for PM40-181K.
PM40-181K has an inductance value of 180 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.
PM40-181K is rated for 102 mA. Current rating helps determine whether the part can carry the expected DC or RMS current without excessive heating or saturation risk.
PM40-181K lists a DC resistance of 9.5Ohm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
PM40-181K uses a package or case of 1812 (4532 Metric). Package size affects PCB footprint, height clearance, thermal behavior, and compatibility with automated assembly.
