Gowanda’s SMRF1812S-220K is a high-quality molded shielded inductor designed for reliable performance in demanding applications. Weighing just 0.15 grams and measuring 4.2 × 3 × 2.9 mm, this surface-mount technology (SMT) component is part of the SMRF1812S series and is suitable for COTS+ grade applications. It features an inductance of 0.22 µH, a direct current resistance (DCR) of 0.078 Ω, and a current rating of 1.6 A DC, with a saturation current of 1.5 A DC. The inductor operates effectively within a frequency range, boasting a self-resonant frequency (SRF) of 310 MHz and a test frequency of 25 MHz, with a minimum Q factor of 50. It offers a tolerance of ±10% and utilizes a ferrite core for enhanced performance. The component is shielded, operates within a temperature range of -55°C to +125°C, and is rated at moisture sensitivity level (MSL) 1. It features Pb termination with a Sn63Pb37 finish and is packaged in tape and reel (T&R) format, ensuring ease of use and integration. Additionally, it is fungal inert, making it suitable for various environmental conditions.
