Parameter Guide
Understand the key electrical and mechanical specifications for PM40-1R0K.
PM40-1R0K has an inductance value of 1 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.
PM40-1R0K is rated for 450 mA. Current rating helps determine whether the part can carry the expected DC or RMS current without excessive heating or saturation risk.
PM40-1R0K lists a DC resistance of 500mOhm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
PM40-1R0K uses a package or case of 1812 (4532 Metric). Package size affects PCB footprint, height clearance, thermal behavior, and compatibility with automated assembly.
