TDK Corp. has introduced a new tool for calculating and selecting EPCOS and TDK film capacitors for PCB mounting. The new CLARA (capacitor life and rating application) tool offers parametric search functionality. This includes capacitance and voltage range as well as for rated voltage, RMS and peak current, temperature, maximum dimensions and volume, approvals, reference standards, and typical applications.
The performance of up to four film capacitors can be simulated under application conditions with one click. The comparisons are displayed in a table, which may include parameters such as operating temperature, DC voltage, AC voltage, peak current, and expected service life.

Safety tolerances also are specified, allowing developers to adjust the configuration in line with their specific requirements, said TDK. A warning is issued if the permitted capacitor parameters are exceeded.
STEP files and SPICE simulation data are available for the majority of capacitors. Application conditions, including personal notes, can be stored for future use. CLARA is linked to the TDK Product Center and the selected capacitors can be ordered through authorized distributors. TDK also offers tools for other devices such as PTC inrush current limiters and magnetics.
