Specifications
Parameter Guide
Understand the key electrical and mechanical specifications for PM20S-R39M.
PM20S-R39M has an inductance value of 390 nH. This value indicates how much magnetic energy the component can store and is one of the first parameters to compare when selecting an inductor.
PM20S-R39M is rated for 465 mA. Current rating helps determine whether the part can carry the expected DC or RMS current without excessive heating or saturation risk.
PM20S-R39M lists a DC resistance of 400mOhm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
PM20S-R39M uses a package or case of 1210 (3225 Metric). Package size affects PCB footprint, height clearance, thermal behavior, and compatibility with automated assembly.
