Gowanda’s SMRF3013-431M is a molded unshielded inductor designed for high reliability in demanding applications. As part of the COTS M83446/32 and M83446/33 series, it features a compact size with dimensions of 7.62 × 2.79 × 3.18 mm and a weight of 0.2 g. This surface-mount technology (SMT) component is suitable for COTS+ application grades, offering an inductance of 4.3 µH and a direct current resistance (DCR) of 1.1 Ω. It supports a current rating of 0.429 A DC and a self-resonant frequency (SRF) of 77 MHz, tested at a frequency of 7.9 MHz with a minimum Q factor of 45. The inductor has a tolerance of ±20% and utilizes a powdered iron core with a lead-based termination type finished with Sn63Pb37. It operates effectively within a temperature range of -55°C to +125°C and is rated at moisture sensitivity level (MSL) 1. Packaged in tape and reel (T&R) format, it is also fungal inert, ensuring durability and reliability in various environments.
