AVRF Series ESD Notch Filters

TDK’s AVRF series filters are ideal for audio equipment with low sound distortion and high sound quality

Image of TDK Corporation's AVRF Series FiltersTDK’s AVRF series ESD notch filters combine electrostatic discharge protection and noise suppression into a single component. A varistor material commonly used for ESD protection has integrated proprietary materials and structure design to not only protect electronic circuits from electrostatic discharge, but to enable highly effective noise suppression by achieving high attenuation for a given frequency. Low audio distortion (THD+N/total harmonic distortion + noise) is advantageous in audio lines such as earphones, microphones, and speakers. AVRF series components are highly effective to counter burst noise (TDMA/TDD) and for measures related to reception sensitivity.

Features
  • Combined ESD and EMI protection
  • High-attenuation characteristics of the Bluetooth® band and Wi-Fi band are highly effective in preventing degradation of the reception sensitivity of radio equipment
  • TDMA noise generated by radio communication can be suppressed
  • Ideal for audio equipment with low sound distortion and high sound quality
Applications
  • Wireless devices that operate in the 2.4 GHz band using wireless LAN and Bluetooth
  • Smartphones
  • Tablets
  • Headsets
  • Hearing aids
  • Smart speakers
