Specifications
Parameter Guide
Understand the key electrical and mechanical specifications for PM20-220K.
PM20-220K has an inductance value of 22 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.
PM20-220K is rated for 110 mA. Current rating helps determine whether the part can carry the expected DC or RMS current without excessive heating or saturation risk.
PM20-220K lists a DC resistance of 4Ohm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
PM20-220K uses a package or case of 1210 (3225 Metric). Package size affects PCB footprint, height clearance, thermal behavior, and compatibility with automated assembly.
