Why low ESR matters in capacitor design

A practical capacitor is a non-ideal component. Its circuit model contains series inductance (ESL) and series resistance (ESR). Although equivalent series resistance is often shown in circuit models as a constant value, it varies depending on operating conditions. ESR is resistance from a combination of energy loss mechanisms under specific operating conditions.

EMI is a serious concern for devices that are externally powered (ones that have a plug) or require signal wires that need to extend outside the device (signal wires that might attach to sensors or input/output devices). The wires that connect to power sources, or I/O points, can act as antennas that will allow EMI to be received (coupled onto them) and enter the device.

Components operating in high vibration and wide operating temperature environments such, as automotive electronics, have to absorb both board flexure stress and stress from the expansion and contraction of solder joints due to thermal shock. Thereby manufactures have developed conductive soft resin-polymer as the thermo-mechanical shock absorber improving connection reliability compare to conventional electrodes. TDK has present its explanation in article below.

Knowles Precision Devices Released 100nF Single Layer Ceramic V-series Capacitor

Knowles Precision Devices are expanding its V-Series of single-layer capacitors by 100nF capacitor. In RF bypassing applications, the 100nF can help eliminate supply line noise. High-frequency monolithic microwave integrated circuit (MMIC) amplifiers with broadband gain need to be protected from RF noise on supply lines. Supply noise can mix with RF signals, impacting signal-to-noise ratios and potentially causing spurious output. A bypass capacitor provides an efficient path to the ground for RF energy on the supply line before it enters a gain stage.
