Gowanda’s SMRF3013-432M is a high-quality molded unshielded inductor designed for COTS applications, specifically M83446/32 and M83446/33. This component features a compact size with dimensions of 7.62 × 2.79 × 3.18 mm and a weight of 0.2 g, making it suitable for surface mount technology (SMT). It offers an inductance of 43 µH, a direct current resistance (DCR) of 4.1 Ω, and a current rating of 0.222 A DC. The inductor operates effectively within a frequency range, with a self-resonant frequency (SRF) of 21 MHz and a test frequency of 2.5 MHz, while maintaining a minimum Q factor of 45. It is built with a ferrite core and has a tolerance of ±20%. The component is designed to withstand extreme temperatures, operating between -55°C and +125°C, and is rated with a moisture sensitivity level (MSL) of 1. It features a lead-based termination type with a Sn63Pb37 finish and is packaged in tape and reel (T&R) format. Additionally, the inductor is fungal inert, ensuring reliability in various environments.
