Gowanda’s SM3-471J is a molded unshielded temperature stable inductor designed for high reliability in electronic applications. Weighing just 0.05 grams and measuring 2.98 × 2.29 × 2.18 mm, this component is part of the SM3 series and is suitable for surface mount technology (SMT). It is classified under the COTS+ application grade, offering an inductance of 4.7 µH with a direct current resistance (DCR) of 1.9 Ω and a current rating of 0.33 A DC. The inductor features a self-resonant frequency (SRF) of 45 MHz and is tested at a frequency of 4 MHz, with a tolerance of ±5%. It utilizes a powdered iron core and has a termination type of Pb with a Sn63Pb37 finish. Operating efficiently within a temperature range of -55°C to +125°C, the SM3-471J is rated at moisture sensitivity level (MSL) 1 and is packaged in tape and reel (T&R) format. Additionally, it is fungal inert, ensuring durability and reliability in various environments.
