MAF0603GW Noise Suppression Filters

TDK MAF0603GWY series noise suppression filters with an ultra‑compact footprint of only 0.6 mm × 0.3 mm × 0.3 mm (L × W × H) are ideal for compact consumer electronics such as smartphones and wearable devices. Electromagnetic noise radiated from audio lines in smartphones, wearable devices, and the like interferes with the built-in antenna and can reduce the receiver's sensitivity. The common countermeasure is chip beads. While effective at suppressing noise, they have the drawback of degrading the audio quality on the audio line, which users may find annoying.

The MAF0603GWY series of noise suppression filters resolves this drawback by employing a newly developed, proprietary low-distortion ferrite material. It introduces just minimal change to audio-line characteristics and significantly reduces audio distortion, eliminating the sound-quality degradation that occurs when chip beads are used. It provides superior high attenuation in the 5 GHz band (impedance up to 3220 Ω at 5 GHz), effectively suppressing noise. Compared with conventional products, it also features lower resistance to reduce attenuation of audio signals and realizes a wide dynamic range.
