KEMET tests ESD capacitors per the AEC-Q200 specification using a certified and calibrated ESD simulator. The ESD simulator uses a precise capacitor and resistor network to deliver a consistent ESD pulse on the test samples which go through a post electrical test to verify pass or fail acceptance criteria. The application of the ESD pulse can be performed either using a direct contact method or air discharge method, depending on the ESD voltage. During the direct contact method, the discharge tip of the ESD gun is placed in direct contact with the capacitor under test when the ESD pulse is applied. During the air discharge method, the tip is placed at a specified distance away from the capacitor when the ESD pulse is applied. Each ESD capacitor is given a classification level depending on its final ESD voltage from the AEC-Q200 testing.
