Parameter Guide
Understand the key electrical and mechanical specifications for SRN4012BTA-1R0M.
SRN4012BTA-1R0M has an inductance value of 1 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.
SRN4012BTA-1R0M is rated for 4.4 A. Current rating helps determine whether the part can carry the expected DC or RMS current without excessive heating or saturation risk.
SRN4012BTA-1R0M lists a DC resistance of 52mOhm Max. Lower DCR usually reduces conduction loss and improves efficiency in power circuits.
SRN4012BTA-1R0M uses a package or case of 1616 (4040 Metric). Package size affects PCB footprint, height clearance, thermal behavior, and compatibility with automated assembly.
