Gowanda’s SMRF1812-222G is a high-quality, molded unshielded inductor designed for demanding applications, particularly in the COTS M83446/39 category. With a compact size of 4.064 × 3 × 2.9 mm and a weight of just 0.15 g, this inductor is ideal for space-constrained environments. It features a surface-mount technology (SMT) mounting type and is constructed with a ferrite core, ensuring reliable performance across a wide operating temperature range of -55°C to +125°C. The inductor offers an inductance of 22 µH, a direct current resistance (DCR) of 3.2 Ω, and a current rating of 0.25 A DC. It also boasts a self-resonant frequency (SRF) of 13 MHz and a minimum quality factor (Q MIN) of 50, tested at a frequency of 2.5 MHz. The product is lead-terminated with a Sn63Pb37 finish, ensuring robust connections, and is packaged in tape and reel (T&R) format for efficient handling. Additionally, it is fungal inert, making it suitable for various environmental conditions.
