ESD Notch Filters

For wireless audio equipment

AVRF series

FEATURES

This is an electronic component that achieves both ESD protection and noise protection.

TDMA noises generated by radio communication can be suppressed.

The high-attenuation characteristics of the Bluetooth band and the WiFi band are highly effective in preventing degradation of the recep-

tion sensitivity of radio equipment.

It is ideal for audio equipment with low sound distortion and high sound quality.

APPLICATION

ESD protection such as sound lines

Sound lines for devices such as smartphones, tablets, headsets, hearing aids, smart speakers and wearable equipments

 (earphones, microphones, and speakers)
