Specifications
Parameter Guide
Understand the key electrical and mechanical specifications for LLSTR-140.
LLSTR-140 has an inductance value of 140 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-140 is rated for 1 A. Current rating helps determine whether the part can carry the expected DC or RMS current without excessive heating or saturation risk.
LLSTR-140 lists a DC resistance of 250mOhm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
LLSTR-140 uses a package or case of Nonstandard. Package size affects PCB footprint, height clearance, thermal behavior, and compatibility with automated assembly.
