Gowanda’s SMRF1812S-101K is a molded shielded inductor designed for high reliability and performance in electronic applications. Weighing just 0.15 grams and measuring 4.2 × 3 × 2.9 mm, this surface-mount technology (SMT) component is part of the SMRF1812S series and is suitable for COTS+ application grades. It features an inductance of 1 µH, a direct current resistance (DCR) of 0.143 Ω, and can handle a current rating of 1.182 A DC with a saturation current of 1.236 A DC. The inductor operates efficiently with a self-resonant frequency (SRF) of 160 MHz and a test frequency of 7.9 MHz, maintaining a minimum quality factor (Q) of 40. It offers a tolerance of ±10% and utilizes a lead-based termination type with a Sn63Pb37 finish. Constructed with a ferrite core and shielded for enhanced performance, it operates within a temperature range of -55°C to +125°C and is rated with a moisture sensitivity level (MSL) of 1. Packaged in tape and reel (T&R) format, the inductor is also fungal inert, ensuring durability and reliability in various environments.
