Automakers are incorporating more multifunctional capabilities into automobiles as they seek to make autonomous driving a reality. Electronic control units (ECUs) for advanced driver assistance systems are consuming more power, and the latest trend is toward ECU integration—installing an ECU close to the engine room or other working part.
For these reasons, the number of electronic devices and components built into cars these days is on the rise, and the reliability of the electronic components used in the electronics is having a growing impact on the reliability of the vehicle overall.

If communication waves from cellular or Wi-Fi sources interfere with and intrude into microphone lines for smartphones or other devices, some of their components will become noise components in audible bands known as "TDMA noise", and may be emitted from speakers as unpleasant sound. Countermeasures which implement combinations of TDK's noise suppression filters and ESD Notch Filters can not only demonstrate outstanding effectiveness at suppressing TDMA noise with no effect on signals, but can also provide a variety of other benefits such as improving cellular or Wi-Fi communication reception sensitivity, and providing countermeasures against ESD (electrostatic discharge).
