Gowanda’s ER10M431JM is a high-quality, reliable electronic component from their M39010 Level-R Molded Unshielded Inductor series. This component weighs 0.283 grams and measures 6.1 × 2.16 × 2.16 mm, designed for through-hole technology (THT) mounting. It is suitable for QPL application grades, offering an inductance of 4.3 µH with a direct current resistance (DCR) of 1.1 Ω and a current rating of 240 A DC. The self-resonant frequency (SRF) is 77 MHz, tested at a frequency of 7.9 MHz, with a minimum quality factor (Q MIN) of 45. It has a dielectric withstanding voltage (DWV) of 1000, 200, 300, and a tolerance of ±5%. This product is classified as Level M, Class 1, with lead-based (Pb) termination and a Sn63Pb37 finish. The core is made of powdered iron, and it is not shielded. It operates within a temperature range of -55°C to +105°C, has a moisture sensitivity level (MSL) of 1, and is packaged in tape and reel (T&R). The component is not fungal inert.
