Specifications
Parameter Guide
Understand the key electrical and mechanical specifications for PM20S-1R2K.
PM20S-1R2K has an inductance value of 1.2 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.
PM20S-1R2K is rated for 390 mA. Current rating helps determine whether the part can carry the expected DC or RMS current without excessive heating or saturation risk.
PM20S-1R2K lists a DC resistance of 650mOhm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
PM20S-1R2K uses a package or case of 1210 (3225 Metric). Package size affects PCB footprint, height clearance, thermal behavior, and compatibility with automated assembly.
