Gowanda’s 040AT2503SM is a high-quality wirewound toroidal inductor, part of the ATSM series, designed for surface mount technology (SMT) applications. This component is ideal for COTS+ grade applications, offering an inductance of 250 µH with a tolerance of ±10%. It features a direct current resistance (DCR) of 0.36 Ω and a self-resonant frequency (SRF) of 2.5 MHz. The inductor supports a current rating of 1.05 A DC, with incremental current levels of 700 mA DC for a 10% inductance change and 1100 mA DC for a 20% change. It is constructed with a Pb termination type and a Sn63Pb37 termination finish, ensuring reliability across a wide operating temperature range from -55°C to +130°C. The component is packaged in tape and reel (T&R) format and has a moisture sensitivity level (MSL) of 1, making it suitable for various demanding electronic applications.
