Gowanda’s ER17S273JR is a high-quality, reliable electronic component, specifically a M39010 Level-R Molded Shielded Inductor. It features a weight of 1.13 grams and dimensions of 9.91 × 3.86 × 3.86 mm. This inductor belongs to the ER17S series and is designed for through-hole technology (THT) mounting. It is QPL application grade, offering an inductance of 270 µH with a direct current resistance (DCR) of 5.8 Ω and a current rating of 115 A DC. The self-resonant frequency (SRF) is 7 MHz, with a test frequency of 0.79 MHz and a minimum quality factor (Q MIN) of 55. It has a dielectric withstanding voltage (DWV) of 1000, 200 and a tolerance of ±5%. The product is classified as Level R, Class 1, with lead-based (Pb) termination and a Sn63Pb37 termination finish. The core material is ferrite, and it is shielded, operating effectively within a temperature range of -55°C to +105°C. It has a moisture sensitivity level (MSL) of 1 and is packaged in tape and reel (T&R), though it is not fungal inert.
