Parameter Guide
Understand the key electrical and mechanical specifications for CWF2012A-330M.
CWF2012A-330M has an inductance value of 33 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.
CWF2012A-330M is rated for 145 mA Max. Current rating helps determine whether the part can carry the expected DC or RMS current without excessive heating or saturation risk.
CWF2012A-330M lists a DC resistance of 4.34Ohm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
CWF2012A-330M uses a package or case of 0805 (2012 Metric). Package size affects PCB footprint, height clearance, thermal behavior, and compatibility with automated assembly.
