Divides components into five grades labeled 0-4. The following chart summarizes the five grades, temperature parameters, and allowable applications for automotive capacitors and components. Grade 4 is the least stringent grade, and Grade 0 is the most stringent. To gain certification, capacitors and other components must pass the following tests:
When choosing an automotive capacitor, designers must not only understand the performance characteristics of different technologies, but also how they’re affected by the operating conditions of different applications. Related To: Vishay Intertechnology
The automotive standard for capacitors and other electronic components arose in the early 1990s as a response to the growth of the personal electronics sector. As electronic devices became more and more pervasive, components were in higher demand.
These capacitors for automotive applications have a capacitance range of 270 µF to 12,000 µF. The rated voltages are 25 VDC and 75 VDC. Package sizes range from 12.5 × 20 mm to 18 × 40 mm, depending on the voltage and capacitance ratings.
However, physical size is only one characteristic of a given capacitor type. For example, although film capacitors are rather large in size, they offer extremely high efficiency and stable electrical characteristics.

The capacitance of the majority of capacitors used in electronic circuits is generally several orders of magnitude smaller than the farad. The most common units of capacitance are the microfarad (μF), nanofarad (nF), picofarad (pF), and, in microcircuits, femtofarad (fF).
