The unshielded construction means the magnetic field extends beyond the component body — keep it away from sensitive traces or other magnetics on the board, or the coupling will shift both inductances. Rated for 355 mA DC with a DCR of 370 mOhm, the I²R loss at full current is about 47 mW. That's manageable in free air, but in a dense layout the self-heating adds to the ambient; the -40 to 105 °C operating range gives some headroom above the 85 °C typical for consumer gear. ## NRND — what it means for your BOM That's the official lifecycle status — the part is still available through distribution for existing production, but you should not drop it into a new board spin. Sourced through independent distribution channels, the LBC2016T4R7M remains orderable against an RFQ. ## Ferrite core and self-resonant frequency The ferrite core material gives this inductor a self-resonant frequency of 45 MHz — well above the 7.96 MHz test frequency. For a 4.7 µH part, that SRF means the inductive impedance holds clean up into the low tens of MHz; beyond that, the parallel capacitance dominates and the part looks capacitive. Keep your switching or signal frequency below roughly one-third of the SRF to stay in the inductive region where the datasheet tolerance and DCR apply. The ±20 % tolerance is wide — typical for power-grade drum cores. That doesn't matter much for a ripple-filter choke where the inductance floor sets the current ripple; it does matter if you're using it in a tuned LC tank or a resonant converter where the frequency shifts with the inductance spread.","metaTitle":"Taiyo Yuden LBC2016T4R7M 4.7 µH Drum Core Wirewound Inductor","metaDescription":"Taiyo Yuden LBC2016T4R7M drum core wirewound inductor, 4.7 µH, 355 mA, 370 mOhm DCR, 0806 SMD.
