Gowanda’s SMRF1812S-331KLF is a high-quality molded shielded inductor designed for reliable performance in various applications. With a compact size of 4.2 × 3 × 2.9 mm and a weight of 0.15 g, it is suitable for surface mount technology (SMT) installations. This inductor belongs to the SMRF1812S series and is classified as COTS+ application grade, ensuring enhanced reliability. It features an inductance of 3.3 µH, a direct current resistance (DCR) of 0.264 Ω, and a current rating of 0.87 A DC, with a saturation current of 0.682 A DC. The inductor operates effectively within a frequency range, with a self-resonant frequency (SRF) of 45 MHz and a test frequency of 7.9 MHz. It offers a minimum quality factor (Q) of 40 and a tolerance of ±10%. The component is RoHS compliant, with Sn100 termination finish, and is constructed with a ferrite core for optimal performance. It is shielded to minimize electromagnetic interference and can operate in temperatures ranging from -55°C to +125°C. The inductor is moisture sensitivity level (MSL) 1 rated, packaged in tape and reel (T&R) format, and is fungal inert, making it suitable for a wide range of demanding environments.
