Gowanda’s 121AT2503VSM is a high-quality vertical mount toroidal inductor designed for reliable performance in electronic applications. Weighing 14.5 grams and measuring 0.83 × 0.625 × 0.9 mm, this component is part of the ATVSM series and features surface mount technology (SMT) for easy integration. It is classified as COTS+ application grade, ensuring suitability for commercial off-the-shelf applications. The inductor offers an inductance of 250 µH with a direct current resistance (DCR) of 0.16 Ω and a self-resonant frequency (SRF) of 1 MHz. It supports a current rating of 2.07 A DC, with incremental current limits of 2200 mA DC for a 10% change and 3200 mA DC for a 20% change. The component has a tolerance of ±10% and features lead (Pb) termination with a Sn63Pb37 finish. It operates effectively within a temperature range of -55°C to +125°C and has a moisture sensitivity level (MSL) of 1, making it suitable for various environmental conditions. The inductor is available in tape and reel (T&R) packaging for efficient handling and assembly.
