Filtering is the practice of blocking or permitting frequencies in circuit stages. Whether decoupling or filtering, KEMET has the solutions necessary for both. Visit our simulation tool K-SIM to investigate capacitor behavior and visit ComponentEdge to find the capacitor right for you.
Decoupling and filtering are two of the most common uses of capacitors. It can be tempting to use the two terms interchangeably but in doing so, some of the key elements of usage can be overlooked. Decoupling is when capacitors are used as on-demand energy supplies for voltage transients of various lengths.
Also, they have a low dielectric constant meaning their capacitance is low for its size. Polyester film capacitors are frequently found in high-current power supplies, EMI filters, and other circuits with little tolerance for ESR/ESL and/or changes in capacitance due to pressure or temperature.
