Gowanda’s MLRF21M272K is a high-quality, reliable electronic component, specifically a M15305 Qualified Molded Unshielded Coil Inductor. It features a weight of 1.5 grams and dimensions of 13.97 × 5.33 × 5.33 mm. Part of the MLRF21M series, it is designed for through-hole technology (THT) mounting and is suitable for QPL application grades. The inductor offers an inductance of 27 µH, a direct current resistance (DCR) of 1.3 Ω, and a current rating of 0.275 A DC. It has a self-resonant frequency (SRF) of 22 MHz and a test frequency of 2.5 MHz, with a minimum quality factor (Q MIN) of 60. The dielectric withstanding voltage (DWV) is rated at 1000, 200, with a tolerance of ±10%. The product level is M, with lead-based (Pb) termination and a Sn63Pb37 termination finish. It utilizes a powdered iron core and is not shielded, operating efficiently within a temperature range of -55°C to +125°C. The component has a moisture sensitivity level (MSL) of 1, is packaged in tape and reel (T&R), and is fungal inert.
