Parameter Guide
Understand the key electrical and mechanical specifications for HCTR-503.
HCTR-503 has an inductance value of 12.5 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.
HCTR-503 is rated for 9.25 A. Current rating helps determine whether the part can carry the expected DC or RMS current without excessive heating or saturation risk.
HCTR-503 lists a DC resistance of 11.4mOhm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
HCTR-503 uses a package or case of Nonstandard. Package size affects PCB footprint, height clearance, thermal behavior, and compatibility with automated assembly.
