Parameter Guide
Understand the key electrical and mechanical specifications for PTHF50-121H.
PTHF50-121H has an inductance value of 50 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.
PTHF50-121H is rated for 4.77 A. Current rating helps determine whether the part can carry the expected DC or RMS current without excessive heating or saturation risk.
PTHF50-121H lists a DC resistance of 30mOhm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
PTHF50-121H uses a package or case of Radial, Horizontal (Open). Package size affects PCB footprint, height clearance, thermal behavior, and compatibility with automated assembly.
