TDK AVRF Series ESD Notch Filters

TDK AVRF Series ESD Notch Filters provide ESD protection and noise filtering for audio lines in compact devices. The integrated proprietary materials and structure design protect electronic circuits from electrostatic discharge and enable highly effective noise suppression by achieving high attenuation for a given frequency. These components have low audio distortion (THD+N/total harmonic distortion + noise), which is ideal in audio lines such as earphones, microphones, and speakers. The AVRF series is highly effective in countering burst noise (TDMA/TDD) and for measures related to reception sensitivity. TDK AVRF Series ESD Notch Filters are well-suited for audio equipment designed for high sound quality. Typical markets include medical/healthcare, information and communication technology, wearables, home appliances, automobiles, and industrial equipment/energy.
