Specifications
Parameter Guide
Understand the key electrical and mechanical specifications for PM20-470K.
PM20-470K has an inductance value of 47 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.
PM20-470K is rated for 60 mA. Current rating helps determine whether the part can carry the expected DC or RMS current without excessive heating or saturation risk.
PM20-470K lists a DC resistance of 7Ohm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
PM20-470K uses a package or case of 1210 (3225 Metric). Package size affects PCB footprint, height clearance, thermal behavior, and compatibility with automated assembly.
