Gowanda’s SMRF1010-391MS is a surface mount epoxy coated chip inductor designed for high reliability applications. This component is part of the SMRF1010 series and is compliant with COTS M83446/04 standards, ensuring quality and performance. With a compact size of 2.28 × 2.28 × 2.16 mm and a weight of just 0.05 g, it is ideal for space-constrained designs. The inductor features an inductance of 3.9 µH, a DCR of 1.55 Ω, and a current rating of 0.25 A DC. It operates effectively within a frequency range, with an SRF of 68 MHz and a test frequency of 7.9 MHz. The component has a Q MIN of 24 and a DWV of 500, 80, with a tolerance of ±20%. It is designed for surface mount technology (SMT) applications, with Pb, RoHS termination type and SnPb termination finish. The core is made of phenolic material, and it is not shielded. It operates reliably across a temperature range of -55°C to +125°C, with a moisture sensitivity level (MSL) of 1, and is available in tape and reel (T&R) packaging.
