The 680 mA current rating and 100 mOhm DCR define the conduction loss and thermal rise in a DC-DC converter input filter or decoupling role — the inductor's self-resonant frequency of 70 MHz keeps the impedance inductive well into the switching noise band. ## NRND — what it means for procurement No pin-compatible drop-in replacement is documented in the LB, C Type series. ## Unshielded construction and layout The LBC3225T4R7MR is unshielded, meaning the magnetic field radiates from the winding. In a dense PCB layout, adjacent traces carrying sensitive analog signals or high-impedance nodes should be kept clear of the inductor's footprint to avoid coupled noise. The 1210 (3225 Metric) footprint is standard — no special pad geometry required beyond the datasheet land pattern. Operating temperature range is -40°C to 105°C, covering industrial ambient conditions. The ±20% tolerance on the 4.7 µH inductance is typical for power-grade wirewound inductors — the DC bias characteristic will shift the effective inductance under load, so the tolerance should be budgeted in the converter's loop stability margin.","metaTitle":"Taiyo Yuden LBC3225T4R7MR 4.7 µH Wirewound Inductor, NRND","metaDescription":"Taiyo Yuden LBC3225T4R7MR wirewound inductor, 4.7 µH, 680 mA, 100 mOhm DCR, 1210 (3225 Metric) package.
