SMT1803-331M

Gowanda’s SMT1803-331M is a high-efficiency, low-profile toroidal inductor designed for demanding applications. Weighing just 1.5 grams, it features compact dimensions of 7.9 × 5.21 × 2.03 mm and is part of the SMT1803 series. This surface-mount technology (SMT) component is classified under the COTS+ application grade, offering an inductance of 3.3 µH with a direct current resistance (DCR) of 0.107 Ω. It supports a current rating of 1.27 A DC and an I SAT of 2.23 A DC, with a tolerance of ±20%. The inductor uses a ferrite core and is not shielded, operating efficiently within a temperature range of -55°C to +125°C. It features Pb termination with a Sn63Pb37 finish, is rated at moisture sensitivity level (MSL) 1, and is available in tape and reel (T&R) packaging.
