It is rated for 65 mA DC with a DCR of 12.3 Ohm, and its self-resonant frequency is 4.5 MHz — above that point the part behaves capacitively, so it is best used in low-pass filters or DC-DC output stages where the ripple frequency stays well below 4.5 MHz. ## NRND lifecycle — plan for a last-time buy For existing BOM lines, this means the part remains available through independent distribution channels, but new designs should select an active alternative. Sourcing is confirmed per RFQ — availability and pricing are quoted at order time. ## Unshielded construction — layout considerations The unshielded ferrite core means the magnetic field radiates from the inductor. In a dense PCB layout, keep sensitive analog traces or high-impedance nodes at least one component width away to avoid coupling. ## Temperature range and bias current Rated for -25°C to 105°C operating temperature, this inductor suits indoor industrial equipment but not automotive under-hood environments. The 65 mA current rating is the DC bias limit at 25°C ambient; derate the current above 85°C to keep the core from saturating and the I²R loss (12.3 Ohm DCR,) from raising the temperature beyond the 105°C ceiling.","metaTitle":"Taiyo Yuden LBC2518T331M 330 µH Unshielded Inductor, NRND","metaDescription":"Taiyo Yuden LBC2518T331M drum core wirewound inductor, 330 µH, 65 mA, 12.3 Ohm DCR, 1007 package.
