Tiny High Voltage Capacitor, ArcShield | Ask An FAE #4

Packing more capacitance at high voltage into a ceramic capacitor needs a cleverly designed electrode pattern. To prevent surface arcing, ArcShield contains a Faraday cage in a 1000 V package as small at 0603.

Derate tantalum capacitors by how much? | Ask An FAE #3

Learn how much to derate polymer and tantalum capacitors. KEMET’s James explains the difference between lifetime and failure rates for tantalum capacitors.

Picking Smart Meter Capacitors | Ask an FAE ep.2

Smart meter capacitors need to have a long operational lifetime. Picking any off-the-shelf X2 capacitor might be an issue. Not all X2 capacitors are designed for a series coupling application, like those found in smart meter power supplies.

Why do ceramic capacitors change with applied voltage? | KEMET Ask an FAE

This episode of Ask an FAE covers why capacitance changes with voltage, how to determine how much change and introduces KEMET’s K-SIM—a capacitor parameter simulator.
