Gowanda’s SMRF1812-330J is a high-quality molded unshielded inductor designed for COTS applications, featuring a compact size with dimensions of 4.064 × 3 × 2.9 mm and a weight of 0.15 g. This surface-mount technology (SMT) component is part of the SMRF1812 series and offers an inductance of 0.33 µH with a tolerance of ±5%. It has a direct current resistance (DCR) of 0.55 Ω and a current rating of 0.604 A DC. The inductor operates effectively within a frequency range, with a self-resonant frequency (SRF) of 250 MHz and a test frequency of 25 MHz, ensuring a minimum Q factor of 40. Constructed with a powdered iron core, it is designed to withstand operating temperatures from -55°C to +125°C and is rated with a moisture sensitivity level (MSL) of 1. The component features Pb termination with a Sn63Pb37 finish and is packaged in tape and reel (T&R) format, ensuring ease of handling and assembly. Additionally, it is fungal inert, making it suitable for various demanding environments.
