Harmonic distortion is a common parameter used to describe the quality of audio or electronic signals. It refers to the presence of unwanted harmonics or additional frequencies in the output signal that were not present in the input signal. These harmonics are typically multiples of the original signal frequency and can distort the waveform, affecting the overall sound quality or performance of the electronic component. Lower harmonic distortion values indicate a cleaner and more accurate output signal, while higher distortion levels can result in a more distorted or altered sound. Manufacturers often specify harmonic distortion levels in percentage or decibels to help users understand the quality of the component's output.

SVHCs are substances that may have serious effects on human health or the environment, and their use is regulated under REACH to ensure their safe handling and minimize their impact.Manufacturers of electronic components need to declare if their products contain any SVHCs above a certain threshold concentration and provide information on the safe use of these substances. This information allows customers to make informed decisions about the potential risks associated with using the components and take appropriate measures to mitigate any hazards.Ensuring compliance with REACH SVHC requirements is essential for electronics manufacturers to meet regulatory standards, protect human health and the environment, and maintain transparency in their supply chain. It also demonstrates a commitment to sustainability and responsible manufacturing practices in the electronics industry.
