Gowanda’s SMT1803-331MLF is a high-efficiency, low-profile toroidal inductor designed for demanding applications. Weighing just 1.5 grams and measuring 7.9 × 5.21 × 2.03 mm, this component is part of the SMT1803 series and features surface-mount technology (SMT) for easy integration. It is classified as COTS+ grade, ensuring reliability in commercial off-the-shelf applications. With an inductance of 3.3 µH, a direct current resistance (DCR) of 0.107 Ω, and a current rating of 1.27 A DC, it is suitable for various electronic circuits. The inductor can handle a saturation current (I SAT) of 2.23 A DC and has a tolerance of ±20%. It is RoHS compliant with Sn100 termination finish and utilizes a ferrite core. Although not shielded, it operates efficiently within a temperature range of -55°C to +125°C and has a moisture sensitivity level (MSL) of 1, making it ideal for tape and reel (T&R) packaging.
