Gowanda’s 121AT2503HCLF is a high-quality, reliable electronic component designed for demanding applications. This horizontal encapsulated toroidal power choke, part of the ATHC series, features a compact design with dimensions of 24.13 × 24.13 × 13.97 mm and a weight of 16 g. It is suitable for surface mount technology (SMT) and offers an inductance of 250 µH with a direct current resistance (DCR) of 0.16 Ω. The component supports a self-resonant frequency (SRF) of 0.9 MHz and a current rating of 2.07 A DC. It can handle incremental current levels with a 10% inductance change at 2200 mA DC and a 20% change at 3200 mA DC. With a tolerance of ±10%, RoHS-compliant termination, and a Sn/Cu finish, it operates efficiently across a temperature range of -55°C to +130°C. The component is rated at moisture sensitivity level (MSL) 1 and is available in bulk packaging.
