Parameter Guide
Understand the key electrical and mechanical specifications for CWF1612A-3R9K.
CWF1612A-3R9K has an inductance value of 3.9 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.
CWF1612A-3R9K is rated for 430 mA Max. Current rating helps determine whether the part can carry the expected DC or RMS current without excessive heating or saturation risk.
CWF1612A-3R9K lists a DC resistance of 1.6Ohm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
CWF1612A-3R9K uses a package or case of 0603 (1608 Metric). Package size affects PCB footprint, height clearance, thermal behavior, and compatibility with automated assembly.
