Different capacitor types reduce ripple voltage on DC-to-DC converters. Axel demonstrates how 4 different capacitor types affect the ripple voltage on a boost or buck regulator. Each bank of capacitors is the same capacitance. However, the ESR and ESL differences cause a different in the output ripple voltage. The capacitor types compared include X7R Ceramic, Aluminum Polymer, Polymer KO-CAP, and Tantalum MnO2.
Flex Suppressor solves EMI issues quickly. If your design does not pass EMI tests, try sticking pieces of Flex Suppressor inside. It can be applied directly to an IC, on the inside of an enclosure, or anywhere you think EMI might be leaking out. Per asks Wilmer to demonstrate how Flex Suppressor works.
Finding the right capacitor does not have to be difficult. That is why we launched the all new ComponentEdge search engine. Whether you want to browse with a mouse (or screen taps) or search using descriptive phrases, we have got you covered.
Packing more capacitance at high voltage into a ceramic capacitor needs a cleverly designed electrode pattern. To prevent surface arcing, ArcShield contains a Faraday cage in a 1,000 V package as small at 0603. Mark explains to James how ArcShield achieves this performance and what it makes it different from other high-voltage ceramic surface mount capacitors.
The market for smartphone apps is exploding, as developers find inventive ways to take advantage of the fantastic features in today’s handsets. These include large, high-resolution color displays, multi-megapixel/HD-video cameras, built-in GPS, and always-on connectivity that enables users to share their experiences instantaneously. How did one of customers solve EMI problems with a Flex Suppressor?
