Class D digital power amplifier inductor is a kind of directional inductor using Class D digital signal processing, which has the advantages of low noise, low stray capacitance and high energy efficiency of traditional oscillation circuit.
As a crucial component in the feedback loop, the inductor has a significant impact on common issues such as differential oscillation and slope feedback in power amplifiers. Therefore, the development of low-noise, low-distortion, and high-efficiency D-class digital amplifier inductors will help improve the distortion rate and frequency response of D-class digital amplifiers, adding a new dimension to the development of the electronic components market.
Modular 2-in-1 structure design, effectively saving space;
Adopting low-loss manganese zinc ferrite core, the core has low losses and can withstand high currents;
Closed magnetic circuit, low humming noise.
Suitable as a digital amplifier (Class D amplifier) LPF inductor;
Supports high output for home theater, AV receivers, small components, etc.
Note:
1. All test data is reference to 25℃ ambient；
2. Test Condition：100kHz，0.1Vrms；
3. ISaturation current：the actual value of DC current when the inductance decrease 25% of its initial value；
4. Temperature rise current：the actual value of DC current when the temperature rise is ΔT40℃(Ta=25℃)；
5. Special remind：Circuit design, component placement, PCB size and thickness, cooling system and etc；
all will affect the product temperature. Please verify the product temperature in the final application.
