SMRF1812T-472M

Gowanda’s SMRF1812T-472M is a molded unshielded temperature stable inductor designed for high reliability in electronic applications. Weighing just 0.15 grams and measuring 4.2 × 3 × 2.9 mm, this component is part of the SMRF1812T series and is suitable for surface mount technology (SMT). It is classified under the COTS+ application grade, offering an inductance of 47 µH with a direct current resistance (DCR) of 9.8 Ω and a current rating of 0.134 A DC. The inductor operates at a self-resonant frequency (SRF) of 10 MHz and is tested at a frequency of 2.5 MHz, with a minimum quality factor (Q) of 35 and a tolerance of ±20%. Featuring a powdered iron core and a lead-based termination type with a Sn63Pb37 finish, it is not shielded but is capable of functioning within a temperature range of -55°C to +125°C. With a moisture sensitivity level (MSL) of 1, it is packaged in tape and reel (T&R) and is fungal inert, ensuring durability and performance in demanding environments.
