3-terminal Feedthrough Filter Protects Automotive ECUs From EMI

TDK Corporation has extended its lineup of 3-terminal feedthrough filters for automotive applications. The new filter measuring 1.6 mm x 0.8 mm x 0.6 mm is qualified according to AEC-Q200 and is suitable for a wide range of decoupling applications to protect automotive ECUs from EMI.

The new YFF18AC0J105M type is available in an IEC 1608 package (EIA 0603) with compact dimensions of just 1.6 mm x 0.8 mm x 0.6 mm and claims the industry’s highest capacitance of 1 µF for a feedthrough filter of its size.

According to TDK, main features and benefits of the component include high capacitance in a compact package, high reliability, and AEC-Q200 compliance.

The component offers a rated current of 2 A and a rated voltage of 6.3 V. Mass production of the components began in January 2018.

“Thanks to its high capacitance and low ESL, the new feedthrough filter from the YFF18AC series can achieve a lower impedance at a frequency of several ten MHz, for example, than five 0.22-µF IEC 1005 MLCCs connected in parallel. The result is a smaller number of components needed and significant space savings”, the company noted.
