Specifications
Parameter Guide
Understand the key electrical and mechanical specifications for PM1812-681J.
PM1812-681J has an inductance value of 680 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.
PM1812-681J is rated for 50 mA. Current rating helps determine whether the part can carry the expected DC or RMS current without excessive heating or saturation risk.
PM1812-681J lists a DC resistance of 30Ohm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
PM1812-681J uses a package or case of 1812 (4532 Metric). Package size affects PCB footprint, height clearance, thermal behavior, and compatibility with automated assembly.
