Audio noise suppression filter

15 June 2016 Circuit & System Protection

When inserted in audio lines, the new MAF1608G filter from TDK keeps THD+N of the audio signals to just 0%. At the same time the miniature component (1,6 x 0,8 x 0,8 mm) features a high rated current of 1,6 A and a low DC resistance of 0,06 Ω. This makes it optimally suited for use in speaker lines where high currents are required. These applications include earphones, speakers and microphones in devices such as smartphones, tablet PC, and portable game consoles.

By utilising a ferrite material with a low distortion factor, TDK was able to reduce sound quality degradation to a level equal to that of a line without a noise filter. This makes it possible to implement noise protection while still extracting the full performance potential of the audio amplifier.
