TDK Corp. recently extended its lineup of EMC components for audio lines by launching the MAF1005G noise suppression filter. The compact (1.0 mm × 0.5 mm × 0.5 mm) filter is well suited for noise suppression in audio lines (e.g., earphones, speakers, and mics) in devices such as smartphones and portable electronics.
Featuring a high attenuation of cellular bands from 700 MHz to 2.5 GHz, the compact filter can suppress the spurious emissions from the cellular bands by up to 50 dB. Moreover, the new MAF1005G filters limit the audio signals’ THD+N to low levels. As a result, sound quality isn’t degradation in audio lines.
