Knowles Precision Devices Introduces Three-Cell Supercapacitors

Knowles Precision Devices, a segment of Knowles Corporation announced that its latest EDLC (Electric Double Layer Capacitor) supercapacitor modules are now available. Based on Knowles' Cornell Dubilier brand DGH and DSF Series supercapacitors, these new cutting-edge capacitors use a three-cell package for higher operating voltages (at up to 9 WVDC) and allow for printed circuit board space savings.

Years of research conducted by ClarityCap, the audio capacitor manufacturer, and the UK-based Institute of Acoustics at the University of Salford, explored how the resonance from the body of a capacitor in a loudspeaker crossover circuit has an audible impact on sound quality. The article details the extensive testing, measurements, and conclusions, which allowed ClarityCap to perfect its manufacturing process, minimizing resonances in capacitors.

Douglas Self shares real experiments when selecting electrolytic capacitors to achieve the lowest distortion. An experiment inspired by his recent audioXpress article, "Optimizing Variable-Frequency Tone Controls," available online. This short piece is an interesting closer examination on the subject for audio circuit designers. Originally published in The Audio Voice newsletter, #453, January 11, 2024.

Mod Electronics is proud to serve the audio industry with Mod Capacitors. Each capacitor is focused on providing the highest performance and quality available to builders, technicians, tinkerers, and musicians. Mod offers hand-crafted oil capacitors, perfect for signal path use, as well as high temperature electrolytic capacitors for solid operation in power supplies and elsewhere. The already vast range of capacitors has been expanded with further options.
