Specifications
Parameter Guide
Understand the key electrical and mechanical specifications for CK21251R0M-T.
CK21251R0M-T has an inductance value of 1 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.
CK21251R0M-T is rated for 220 mA. Current rating helps determine whether the part can carry the expected DC or RMS current without excessive heating or saturation risk.
CK21251R0M-T lists a DC resistance of 260mOhm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
CK21251R0M-T uses a package or case of 0805 (2012 Metric). Package size affects PCB footprint, height clearance, thermal behavior, and compatibility with automated assembly.
