Filters boast broad capacitance & temperature spectrum
A series of 3-terminal feedthrough filters, designed to meet automotive demands for EMC components in emerging safety and infotainment applications, has been introduced by TDK Corporation. Available in case sizes EIA 0603 to EIA 1206, the filters have rated capacitance values ranging from 22pF to 1μF and rated voltages from 10V to 100V.
Able to withstand temperatures of up to 125 °C, the components are rated for high currents up to 10A making them suited for a wide range of noise suppression applications in automotive electronics. The broad capacitance and high reliability of the components fulfil requirements for EMC filtering, even in applications connected directly to the battery.
The device series responds to the growing requirements of noise suppression, as more and more vehicles offer new and sophisticated safety features such as collision avoidance systems. These applications employ GHz band radar and camera sensors for image recognition to detect an imminent crash, warn the driver and sometimes even take action autonomously to avoid the crash. As a result, these circuits operate at higher frequencies and clock rates than is typical in cars up until now, and this drives the need for components to suppress the conducted noise.
Mass production is slated to begin in January 2015.
