TDK Corporation has expanded the MAF1005G series of noise suppression filters for audio lines with four new MAF1005GAD-D types, which, thanks to their low DC resistance, feature a high rated current of up to 1.25 A.
The new types employ TDK's proprietary low-distortion ferrite which enables the new components to suppress noise at cellular frequencies from 600 MHz to 2.7 GHz and ensure high audio quality. Thanks to their high

Available in case size IEC 1005, the new noise suppression filters have miniaturized dimensions of just 1.0 mm x 0.5 mm x 0.5 mm and feature a performance approaching that of the much larger MAF1608G series in IEC 1608. Mass production of the components starts in September 2018.
With this series extension, TDK now offers a broad lineup of noise suppression filters for cellular band frequencies, Class D amplifiers (100 MHz to 400 MHz) and FM band frequencies (66 MHz to 108 MHz). TDK will continue to expand its portfolio for more target band frequencies and further miniaturization.
