The 45 mA current rating and 36.4 Ohm max DCR define the DC bias point — at full rated current, the copper loss alone is about 73 mW, a factor in thermal budgeting for the 1007 package. Unshielded construction means the magnetic field extends beyond the component body. In a dense layout, adjacent traces or low-impedance loops within the near field may couple noise; keep sensitive routing at least one body width away. ## Self-resonant frequency and test conditions Self-resonant frequency is 3 MHz, measured with the inductance test at 796 kHz. Above SRF, the impedance becomes capacitive — this inductor is suited for DC-DC output filtering and low-frequency EMI suppression below 2 MHz, not for RF tank circuits. ## NRND lifecycle — sourcing reality This means the part is still available for existing BOM lines but is not intended for new builds.","metaTitle":"Taiyo Yuden LBC2518T681MV Wirewound Inductor, 680 µH, 45 mA","metaDescription":"Taiyo Yuden LBC2518T681MV wirewound inductor, 680 µH, 45 mA, 36.4 Ohm DCR, NRND.
