Specifications
Parameter Guide
Understand the key electrical and mechanical specifications for CTM1F-221J.
CTM1F-221J 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.
CTM1F-221J is rated for 52 mA. Current rating helps determine whether the part can carry the expected DC or RMS current without excessive heating or saturation risk.
CTM1F-221J lists a DC resistance of 21Ohm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
CTM1F-221J uses a package or case of Axial. Package size affects PCB footprint, height clearance, thermal behavior, and compatibility with automated assembly.
