TDK Corporation has developed a new series of 3-terminal feedthrough filters that are designed to meet the automotive industry’s demands for EMC components in emerging safetyClass X capacitors are used in “across-the-line” applications where their failure would not lead to electric shock. Class X safety caps are used between the “live” wires carrying the incoming AC current. In this position, a capacitor failure should not cause any electrical shock hazards, rather, a capacitor failure “between-the-lines” would usually cause a fuse or circuit breaker to open. and infotainment applications.
The new components are available in case sizes EIA 0603 (1.6 mm x 0.8 mm) to EIA 1206 (3.2 mm x 1.6 mm) with rated capacitanceThat property of a system of conductors and dielectrics which permits the storage of electricity when potential difference exists between the conductors. Its value is expressed as the ratio of a quantity of electricity to a potential difference. A capacitance value is always positive. values ranging from 22 pFUnit of capacitance. The basic unit of a measure of a capacitor. A capacitor charged to 1 volt with a charge of 1 coulombA coulomb is the unit of electric charge. It is named after Charles-Augustin de Coulomb.1 coulomb is the amount of electric charge transported by a current of 1 ampere in 1 second. It can also be defined in terms of capacitance and voltage, where one coulomb is defined as one farad of capacitance times one volt of electric potential difference. would have a capacitance of 1 farad. 1 microF = .000001 Farads. to 1 μFUnit of capacitance.

The robust new components, which can withstand temperatures of up to 125 °C and are rated for high currents up to 10 A, are thus well suited for a wide range of noise suppression applications in automotive electronics. Thanks to their high reliability, the new components with their broad capacitanceThat property of a system of conductors and dielectrics which permits the storage of electricity when potential difference exists between the conductors.

Mass production is slated to begin in January 2015.
TDK’s market-leading experience and know-how in automotive MLCCs enabled the development of the new 3-terminal feedthrough filter series, which contribute to the safetyClass X capacitors are used in “across-the-line” applications where their failure would not lead to electric shock.

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.
The new highly reliable 3-terminal feedthrough filters extend the growing range of MLCCMultiple-layer capacitors interleave dielectric and electrode layers. This type of capacitor has increased current handling capacity, higher Q, and lower internal series resistance than conventional capacitors of the same size and capacitance.-based components for automotive electronics. TDK will continue to expand its product range for the automotive sector, one of the company’s key markets for the future.
