Parameter Guide
Understand the key electrical and mechanical specifications for 4379R-105KS.
4379R-105KS has an inductance value of 1 mH. This value indicates how much magnetic energy the component can store and is one of the first parameters to compare when selecting an inductor.
4379R-105KS is rated for 47 mA. Current rating helps determine whether the part can carry the expected DC or RMS current without excessive heating or saturation risk.
4379R-105KS lists a DC resistance of 22Ohm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
4379R-105KS uses a package or case of 2-SMD. Package size affects PCB footprint, height clearance, thermal behavior, and compatibility with automated assembly.
