Gowanda’s 121AT7502HC is a high-quality horizontal encapsulated toroidal power choke designed for reliable performance in electronic applications. This component, part of the ATHC series, features a compact design with dimensions of 24.13 × 24.13 × 13.97 mm and a weight of 16 grams. It is suitable for surface mount technology (SMT) and offers an inductance of 75 µH with a direct current resistance (DCR) of 0.045 Ω. The choke operates efficiently with a self-resonant frequency (SRF) of 2 MHz and a current rating of 3.9 A DC. It can handle incremental current levels with a 10% inductance change at 3900 mA DC and a 20% change at 5800 mA DC. The component maintains a tolerance of ±10% and features a lead-based termination type with a Sn63Pb37 finish. It is designed to operate in a wide temperature range from -55°C to +130°C and has a moisture sensitivity level (MSL) of 1, making it suitable for various demanding environments. The 121AT7502HC is available in bulk packaging, ensuring ease of integration into manufacturing processes.
