Specifications
Parameter Guide
Understand the key electrical and mechanical specifications for LLSTR-450.
LLSTR-450 has an inductance value of 450 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.
LLSTR-450 is rated for 550 mA. Current rating helps determine whether the part can carry the expected DC or RMS current without excessive heating or saturation risk.
LLSTR-450 lists a DC resistance of 850mOhm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
LLSTR-450 uses a package or case of Nonstandard. Package size affects PCB footprint, height clearance, thermal behavior, and compatibility with automated assembly.
