Gowanda’s SMRF1812-121M is a molded unshielded inductor designed for high reliability in demanding applications. As part of the SMRF1812 series, it features a compact size with dimensions of 4.064 × 3 × 2.9 mm and a weight of just 0.15 g. This surface-mount technology (SMT) component is ideal for COTS+ application grades, offering an inductance of 1.2 µH and a direct current resistance (DCR) of 0.55 Ω. It supports a current rating of 0.604 A DC and a self-resonant frequency (SRF) of 80 MHz, tested at a frequency of 7.9 MHz with a minimum Q factor of 50. The inductor has a tolerance of ±20% and utilizes a ferrite core with a lead-based termination type finished with Sn63Pb37. It operates effectively within a temperature range of -55°C to +125°C, has a moisture sensitivity level (MSL) of 1, and is packaged in tape and reel (T&R) format. Additionally, it is fungal inert, ensuring durability and reliability in various environments.
