Some circuits, particularly those used in high frequencies, can be grossly affected by high ESR. Many of today’s switching power supplies operate at high frequencies, and are subject to self-heating ...

The circuit shown here tackles ESL/ESR measurement of capacitors by using a mercury-wetted relay (Fig. 1). In this circuit, the relay is employed as a fast closing switch.

This is where a not-too-low equivalent series resistance (ESR) is actually a good thing, because it helps to dampen those resonances.

Expanding the BestCap series is an ultra-low ESR double layer capacitor with an expanded temperature range from -40ºC to 75ºC. Groomed for wireless applications, the capacitor ...

Joining Murata’s ECAS series of polymer aluminum electrolytic capacitors is a device that boasts low equivalent series resistance of 4.5 mΩ.

“The new UQCS Series MLC chip exhibits significantly lower ESR values and higher series resonance values, making it ideal for applications with high current carrying capabilities and high ...
