Gowanda’s SMT1803-471MLF 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 under the COTS+ application grade, offering an inductance of 4.7 µH with a direct current resistance (DCR) of 0.125 Ω. The inductor supports a current rating of 1.18 A DC and a saturation current (I SAT) of 1.81 A DC, with a tolerance of ±20%. It is RoHS compliant with Sn100 termination finish and utilizes a ferrite core. Although it is not shielded, it operates effectively within a temperature range of -55°C to +125°C and has a moisture sensitivity level (MSL) of 1, making it suitable for various high-reliability applications. The product is available in tape and reel (T&R) packaging for efficient handling and assembly.
