ESR Losses In Ceramic Capacitors

by Richard Fiore, Director of RF Applications Engineering – American Technical Ceramics In the world of RF ceramic chip capacitors, Equivalent Series Resistance (ESR) is often considered to be the single most important parameter in selecting the product to fit the application. ESR, typically expressed in milliohms, is the summation of all losses resulting from […]

Circuit Designer’s Notebook: Effective Capacitance vs Frequency

by Richard Fiore, Director, RF Applications Engineering – American Technical Ceramics Corp. It is generally assumed that the capacitance value selected from a vendor’s catalog is constant over frequency. This is essentially true for applications with applied frequencies that are well below the capacitor’0s self-resonant frequency. However, as the operating frequency approaches the capacitor’s self-resonant […]
