Gowanda’s 121AT2502HC is a high-quality Horizontal Encapsulated Toroidal Power Choke designed for surface mount technology (SMT) applications. This component, part of the ATHC series, features an inductance of 25 µH and a direct current resistance (DCR) of 0.017 Ω. It supports a current rating of 6.34 A DC and has a self-resonant frequency (SRF) of 5 MHz. The choke is capable of handling incremental current levels with a 10% inductance drop at 7000 mA DC and a 20% drop at 10500 mA DC. It is constructed with a lead (Pb) termination type and a Sn63Pb37 termination finish, ensuring reliable performance across a wide operating temperature range from -55°C to +130°C. With a moisture sensitivity level (MSL) of 1, it is packaged in bulk, making it suitable for various industrial applications requiring precision and durability.
