Construction

Aluminum Capacitors

Aluminum Hybrid Polymer capacitors combines the technical advantages of aluminum electrolytic (e.g.: low leakage current) and polymer capacitors (e.g.: low ESR, high ripple current). These advantages can be realized through the mixture of the liquid electrolyte and the solid polymer.

Measurements

Redexpert

With the help of REDEXPERT you will find the right capacitor based on your technical requirements. The tool supports, for example, with measured values for capacitance, impedance, ESR and dissipation factor (DF). The ability to compare individual components with each other in terms of measured values enables convenient component selection.

REDEXPERT

Lifetime

Lifetime Calculator  

With this tool you can calculate your maximum expected lifetime. Depending on the product family, a different formula is used for the calculation. This calculator can be found in the aluminum capacitor module on the REDEXPERT platform.

Lifetime Calculator

Expected Lifetime vs. Temperature  

In this graph you can find the difference in expected lifetime between our different product families. The curves are based on the different formulas and the endurance of this product. The lifetime table and formula can be found in the information sheet.

Introduction to the capacitor technologies and how to use them

Capacitors make up two thirds of all electronic components and there is a huge diversity of technologies which can overwhelm young engineers. All capacitors store electrical energy in the electrical field created in a dielectric material and they are used for very diverse applications like voltage stability and filtering. How that works differs between tiny MLCCs and huge electrolytic cells, from pF ratings up to the hundreds of Farads in supercapacitors. In this presentation, we introduce different capacitor solutions taking into account the advantages and disadvantages and with a focus on the final application.
