TDK presents the MHF1608 series of filters for interference in the short-wave range for use in automotive applications.
Series production began in September 2020 and the interference suppression filters are installed in the signal lines for electronic control units in automotive applications, including car audio, navigation and battery management systems. The signal paths of these applications are often affected by conducted and radiated interference and other effects. To suppress these interferences, an SMD ferrite is usually inserted for the RF range from a few dozen MHz to several GHz. The MHF series uses a newly developed ferrite material with high loss and high permeability for high impedance from 300 kHz to 30 MHz, even lower than before, to minimize and limit interference. Replacing conventional SMD ferrites with this new TDK series allows manufacturers to reduce the number of components. Other features include a wide temperature range of -55°C to +125°C and AEC-Q200 qualification.
