Capacitors don't always specifically say the name of the company on them and their logos can change throughout the years making identifying manufacturers a challenge. This page aims to catalog capacitor brand logos for easing identification.
A note on submissions, please do not copy/paste logo images from other websites here as they will have their own copyrights. The only acceptable sources for existing images are photographs you took, tracings of logos, press kits from the manufacturer's website, and other images with permissible licenses. The preference for submissions is to be flat black and white images with a black logo on a white background and the manufactures name printed next to the logo. However photo submissions are acceptable provided the picture is clear enough that a recreation of the logo can be made.
