    Product Description
    Power Inductor For Digital Amplifier‌

    The ‌High Quality Class-D Inductor HDA‌ is a premium ‌Power Inductor‌ engineered for high-performance audio systems. Utilizing advanced ‌Class D Inductor‌ technology, it combines magnetically shielded construction (for ultra-low radiation noise) with super-high current handling and minimal resistance to deliver pristine sound quality. 

    inductor for class d amplifier

    Optimized for ‌class d amp inductor‌ applications like digital amplifiers and car audio systems, this ‌Power Inductor‌ operates reliably across -40℃ to +130℃ and complies with RoHS standards.

    Key Features‌

    • ‌Low Noise & High Efficiency‌:
      • The ‌Class D Inductor HDA‌’s shielded design reduces radiation noise, while its ‌Power Inductor‌ architecture supports super-high current (e.g., car audio amplifiers).
    • ‌Thermal Resilience‌:
      • Stable performance from -40℃ to +130℃, ideal for ‌Servo class d output inductor‌ applications in industrial audio equipment.
    • ‌Broad Compatibility‌:
      • Works seamlessly as a ‌Class D Amp Inductor‌ in home theaters, digital amps, and automotive sound systems.

    Applications‌

    • ‌Car Audio Systems‌:
      • ‌Class D Inductors‌ minimize distortion in high-power car amplifiers.
    • ‌Home Theater & TVs‌:
      • ‌Servo Class D Output Inductors‌ enhance clarity in 5.1ch surround sound and LCD/PDP TV audio modules.
    • ‌Industrial Audio Equipment‌:
      • ‌Power Inductors‌ ensure reliable current handling in rugged environments.
    • ‌Digital Amplifiers‌:
      • ‌Class D Amp Inductors‌ optimize efficiency and thermal management.
