Specifications
Parameter Guide
Understand the key electrical and mechanical specifications for LLST-400.
LLST-400 has an inductance value of 400 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.
LLST-400 is rated for 280 mA. Current rating helps determine whether the part can carry the expected DC or RMS current without excessive heating or saturation risk.
LLST-400 lists a DC resistance of 700mOhm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
LLST-400 uses a package or case of Nonstandard. Package size affects PCB footprint, height clearance, thermal behavior, and compatibility with automated assembly.
