Low core loss (loss ≤0.1W/kg at 100kHz) can reduce transformer heat generation and prevent signal distortion caused by temperature rise, making it particularly suitable for scenarios with long-term high-power output (such as stage sound equipment). ? Case: Some high-end tube amplifiers (electron tube amplifiers) use nanocrystalline transformers to optimize the transparency of mid-frequency vocal.SpecificationAudio isolation transformerApplication scenarios:Power inductors and filter elements:Application scenarios: Signal isolation in recording studios and broadcasting equipment, eliminating grounding loop interference. ? Advantages: The high magnetic permeability reduces the turns ratio of the transformer, lowers the distributed capacitance (≤100pF), reduces the crosstalk of high-frequency signals, and ensures the purity of audio signals (such as the background noise control of human voice recording).Class D amplifiers (digital power amplifiers) Application scenarios: Output filter inductors for Class D power amplifiers in car audio systems and home theaters. ? Advantages: High saturation magnetic induction intensity (Bs≥1.2T), capable of withstanding large currents (such as above 10A), avoiding clipping distortion caused by inductor saturation, and suitable for high-frequency PWM signals of Class D power amplifiers (200kHz~1MHz). The low core loss has a significant advantage at high frequencies. Compared with ferrite inductors, it can increase the efficiency of power amplifiers by 3% to 5% (for example, from 90% to over 93%), reducing energy waste.Technical HighlightsPacking & DeliveryStandard Export Pack:OEM Services:Company ProfileNanjing Evergrowing Resources Co.,LimitedFocus: Innovative available audio since 2015Capacity: 50,000 units/monthClients: Supplying 12 European audio brands
