TDK introduces ESD and EMI combined protection for audio equipment

TDK Corporation has expanded its lineup of chip varistors with the new AVRF101U6R8KT242 for audio equipment, which offers both ESD and EMI protection.

This product of TDK is intended for audio equipment that uses wireless communications in the 2.4 GHz band. Thanks to optimization of its capacitance of 6.8 pF, the multilayer component features high attenuation at this frequency and is able to effectively suppress the generated TDMA noise and thus improve receiver sensitivity.

TDKThe recent product by TDK provides excellent ESD protection according to IEC61000-4-2, Level 4 and has a maximum permissible circuit voltage of 28 V DC, making it suitable for high power class-D amplifiers.

Key applications of TDK’s product include smartphones, speakers and other wireless devices that operate in the 2.4-GHz band using wireless LAN and Bluetooth, for example.

Moving forward, TDK will continue to expand the product lineup in terms of chip sizes, bandwidth support range, and other specifications, in order to support a wide range of applications.
