The HDA1931A Series High Current Power Inductor features a flat-wire through-hole (DIP) construction and a magnetically shielded design, specifically engineered for demanding audio applications such as Class-D digital power amplifiers, automotive audio systems, LCD/PDP TVs, and 5.1-channel home theater systems.
Optimized for high-fidelity audio performance, the HDA1931A series delivers low distortion, ultra-low DC resistance (DCR), and high current capability with rated currents of up to 18 A. It is an ideal power inductor for designers seeking efficient power conversion and superior sound quality in high-performance audio equipment.
Q: What is the function of the HDA1931A series in Class-D amplifiers?
A: The HDA1931A series functions as an output choke in Class-D amplifiers. Working with the amplifier's output stage, it filters high-frequency switching noise and restores a clean audio signal, making it a key component for achieving high-fidelity sound quality.
Q: Why is the HDA1931A series suitable for audio applications?
A: The series is optimized with advanced core materials and a flat-wire winding structure to minimize core loss and distortion. Its magnetically shielded design also reduces radiated EMI, ensuring clear, low-distortion audio output.
Q: What is the difference between rated current and allowable current?
A: Rated current is determined by the maximum permissible temperature rise (typically 40°C), while allowable current is based on the maximum acceptable inductance drop (typically 20–30%). Both specifications should be considered during circuit design.
Q: What are the advantages of the flat-wire winding structure?
A: Compared with round-wire windings, the flat-wire construction provides higher copper fill factor, lower DC resistance (DCR), higher current-carrying capability, and improved heat dissipation within the same package size.
