A Comprehensive Guide to Buying Supercapacitors

Your Guide to buying the best Supercapacitors

Overview

Supercapacitors, also known as ultracapacitors, are a type of energy storage device that is becoming increasingly popular in a variety of applications. This buying guide will provide you with insight to help you make an informed decision when purchasing a supercapacitor. We will look at the different types of supercapacitors available, their various performance characteristics, and how to find the right supercapacitor for your specific needs. With this guide, you can find the supercapacitor that best meets your requirements and budget.

Key features

  1. Capacitance – The capacitance of a supercapacitor determines the amount of energy it can store. It is measured in Farads, and shoppers should consider the specific capacitance needed for their application.
  2. Voltage Rating – Supercapacitors have a range of voltage ratings, and shoppers should note the maximum voltage they need for their application.
  3. Leakage Current – The leakage current of a supercapacitor is the amount of current that the capacitor draws when it is sitting idle. Low leakage current is ideal, as it indicates a capacitor that will have a longer lifespan.
  4. Temperature Range – Supercapacitors should have a wide temperature range that is suitable for the environment in which they will be used.
  5. Size – Supercapacitors come in a variety of sizes, and shoppers should consider the physical dimensions of the capacitor in relation to their application.
  6. Manufacturer – It is important to select a reputable manufacturer when purchasing a supercapacitor. Reputable manufacturers will provide quality components that are designed to last.

Trivia

In 2018, a German company unveiled a prototype electric car powered entirely by supercapacitors. The car has no battery but can still travel up to 186 miles on a single charge and can be recharged in just 15 seconds. The car is also surprisingly light, weighing in at just 467 kg – a third less than a typical electric car. The company hopes to bring the car to market later this year. Source
