Gowanda’s 28MG471K is a molded non-magnetic inductor designed for medical applications, offering high reliability and performance. Weighing 2.65 grams and measuring 22.86 × 7.137 × 7.137 mm, this inductor is part of the 28MG series and features through-hole technology (THT) mounting. It provides an inductance of 4.7 µH with a Q minimum of 60, tested at a frequency of 7.9 MHz. The device has a direct current resistance (DCR) of 0.56 ohms and a self-resonant frequency (SRF) of 90 MHz, with a current rating of 0.86 A DC. It maintains a tolerance of ±10% and uses a lead-based termination type with a Sn63Pb37 finish. The core is non-magnetic, and the inductor is not shielded, operating efficiently within a temperature range of -55°C to +125°C. It is rated at moisture sensitivity level (MSL) 1 and is available in tape and reel (T&R) packaging.
