High-current noise suppression filters for audio lines
The MAF1005G series of noise suppression filters for audio lines has been expanded by TDK Corporation, with four new MAF1005GAD-D types, which, thanks to their low DC resistance, feature a high rated current of up to 1.25A.
The new types employ TDK's proprietary low-distortion ferrite that enables the new components to suppress noise at cellular frequencies from 600MHz to 2.7GHz and ensure high audio quality. Thanks to their high rated current, the new components are suitable especially for the audio lines for external speakers of smartphones and other compact communication devices as well as for headphones and microphones.
Available in case size IEC 1005, the new noise suppression filters have miniaturised dimensions of just 1.0x0.5x0.5mm 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 to 400MHz) and FM band frequencies (66 to 108MHz). TDK will continue to expand its portfolio for more target band frequencies and further miniaturisation.
