Specifications
Parameter Guide
Understand the key electrical and mechanical specifications for WCL2520-221-R.
WCL2520-221-R has an inductance value of 220 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.
WCL2520-221-R is rated for 20 mA. Current rating helps determine whether the part can carry the expected DC or RMS current without excessive heating or saturation risk.
WCL2520-221-R lists a DC resistance of 18Ohm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
WCL2520-221-R uses a package or case of 1008 (2520 Metric). Package size affects PCB footprint, height clearance, thermal behavior, and compatibility with automated assembly.
