It carries an 80 mA current rating and an 8.4 Ohm DC resistance, with a ±20 % inductance tolerance. Packaged in the 1007 (2518 Metric) SMT case measuring 2.50 x 1.80 mm with a 2.00 mm seated height, it is suited for surface-mount assembly on power-supply filter or DC-DC converter output stages where board height is constrained. ## Electrical envelope and thermal limits The self-resonant frequency is 5.5 MHz, and inductance is tested at 796 kHz — the part operates below that SRF in typical low-frequency filtering roles. Operating temperature spans -25 °C to 105 °C, covering most industrial and consumer environments without special derating. Because it is unshielded, the magnetic field couples into nearby traces or components — layout should maintain clearance from sensitive analog or RF nodes to avoid parasitic coupling. ## Active production — sourcing posture Pricing and lead time are confirmed at RFQ against the BOM quantity. The tape-and-reel packaging suits automated pick-and-place, with lot traceability maintained through the authorized supply chain.","metaTitle":"Taiyo Yuden LBC2518T221M 220 µH Unshielded Wirewound","metaDescription":"Taiyo Yuden LBC2518T221M drum-core wirewound inductor, 220 µH, 80 mA, 8.4 Ohm DCR, unshielded, -25 to +105°C.
