We have introduced new versions of our KO-CAP Tantalum Polymer capacitors that can go far beyond what has been expected of them. Our latest formulation of materials and construction techniques has allowed us to develop a 470 uF, D-case capacitor at 2.5 V. Even more impressive, the amount of cap contained therein has single digit ESR.
Polymer Tantalum Capacitors Continue to Toughen Up to Meet Automotive Demands
Tuesday, June 4th, 2019
New materials and manufacturing processes enable polymer tantalum capacitors to pass automotive AEC-Q200 stress test requirements, as well specific electrical transient tests. Although the market supply chain challenges with high CV MLCC‘s availability and new automotive requirements with electrification, digitalization, and autonomous driving are bringing new opportunities.
For all Class II and III capacitors (X7R, X5R, etc.), there is an unavoidable phenomenon where capacitance changes at a constant rate over time. The effect is called aging and this Tech Topic will provide answers to the following questions: What is aging? What causes aging? Is aging reversible?
Why Derate? Derating is a term that is frequently used but not always in the right context or for the right reasons. Oftentimes one or more parameter of a device is derated to improve some type of performance. Said performance metric could be quiescent current or it could be life. In the case of tantalum capacitors voltage is derated in an effort to improve the life of the capacitor.
Join us in Nuremberg from May 7-9 to discuss Power electronics, renewable energy and energy management. We will have interactive activities and new products to share at Hall 9 Booth #403.
