Rated for 630 mA continuous current with a DC resistance of 130 mOhm, the part is sized for low-to-moderate current rails in DC-DC converter output filters and signal conditioning circuits. ## Parametric fit — inductance, current, and self-resonant frequency The 2.2 µH ±20% tolerance at 7.96 MHz test frequency suits it for switching regulator output chokes in the 1-5 MHz switching range, where the 68 MHz self-resonant frequency provides adequate margin before parasitic capacitance dominates. The 630 mA current rating is the saturation-limited continuous current — the unshielded ferrite core saturates gradually above this point, so the inductance drops off smoothly rather than abruptly. 130 mOhm DCR at room temperature produces an I²R loss of about 52 mW at full rated current — acceptable for most board-level power stages but worth derating if the ambient temperature approaches the 105°C upper limit. ## Package and board-fit — 1007 footprint constraints The 2.50 mm x 1.80 mm footprint with a 2.00 mm seated height fits the standard 1007 (2518 Metric) land pattern — the same footprint used by many 2.2 µH wirewounds from other manufacturers, easing second-sourcing. Unshielded construction means the inductor radiates magnetic flux — keep sensitive traces or low-level analog circuitry at least 2-3 mm away from the body to avoid coupling. Operating temperature from -40°C to 105°C covers industrial control, automotive cabin, and telecom infrastructure environments without needing a wider-grade part.","metaTitle":"Taiyo Yuden LBC2518T2R2M 2.2 µH Unshielded Wirewound","metaDescription":"Taiyo Yuden LBC2518T2R2M drum core wirewound inductor, 2.2 µH ±20%, 630 mA, 130 mOhm DCR, 1007 package.
