TDK株式会社开发出了全新的音频线噪音滤波器 MAF1005G系列产品，为其音频线用EMC产品阵容添加了三种新型产品，尺寸仅为1.0 mm x 0.5 mm x 0.5 mm。该小型化音频线噪音滤波器设有从700兆赫至2.5千兆赫蜂窝频带的高衰减，噪音电平最大可抑制50dB。此外，该新款噪音滤波器与TDK在 2016年5月推出的MAF1608G产品一样，可将音频信号的失真控制在业内最低水准*，因此MAF1005G噪音滤波器不会引起音频线中的音质劣化。由于该产品尺寸小，衰减性能优良，特别适用于诸如智能电话，平板电脑和便携式游戏机等设备的音频线(耳机，扬声器，麦克风)噪音抑制。

通过使用低失真铁氧体材料，TDK可降低音质恶化并等同于不插入噪音滤波器时。这使得其可以实现噪音防护的同时，仍然发挥音频放大器的最大性能潜力。该产品已于2016年8月开始量产。
