TDK Product Features
ESD notch filters from TDK combine electrostatic discharge protection and noise suppression. The main component is a varistor material commonly used for ESD protection, making it possible to reliably protect electronic circuits from electrostatic discharge. Proprietary materials design and structure design realize outstanding attenuation for a given frequency, enabling highly effective noise suppression. Low audio distortion (THD+N/total harmonic distortion+noise) is advantageous in audio lines (such as for earphones, microphones, and speakers), and the components are highly effective to counter burst noise (TDMA/TDD) and for measures related to reception sensitivity. Ideal for audio equipment designed for high sound quality.
