Filtering out common mode noise with monolithic EMI filters

By Design World, Johanson Dielectrics Posted On 12.8.2019

By Mike Santora

Many factors increase the amount of “noise” interference that can damage or disturb the functionality of electronic devices. Today’s automobiles are a prime example. In a single vehicle, you can find Wi-Fi, Bluetooth, satellite radio, GPS systems, and that’s just the beginning. To manage this noise interference, the industry typically uses shielding along with EMI filters to eliminate unwanted noise. But now some of the traditional solutions for eliminating EMI/RFI are no longer sufficient. (more…)

Capacitors High Reliability Testing

By Knowles Precision Devices Posted On 2.8.2019

Source: Knowles Precision Devices blog

Product durability and accelerated life cycle testing are all methods of determining the reliability of a product before release. By subjecting the capacitor to elevated conditions far beyond its normal operational ranges, we seek to discover any defects or points of failure to better inform customers about the limitations of the unit.

An introduction to capacitor based Power Factor Correction circuits

By Capacitor Faks Posted On 29.7.2019

Source: Capacitor Faks blog

Some of the AC power consumed by inductive loads is used to maintain magnetic reversals due to phase shift between current and voltage. This energy can be considered as wasted energy since it is not used in performing useful work. Power factor correction circuits are used to minimize reactive power and enhance the efficiency with which inductive loads consume AC power. Capacitors are essential components in power factor compensation circuits, and this article will explore some design considerations when using these components for power factor correction. (more…)

Capacitors are used in electronic circuits for a wide range of applications including coupling, timing, filtering, decoupling, and wave shaping. These passive components come in a wide array of shapes, sizes, and designs, and it is usually not easy to identify a component that meets the specific requirements of an application. In most electronic circuits, the overall performance of a circuit is greatly determined by the choice of capacitors. (more…)

3V CAPXX Supercapacitors Characteristics for Wearables, Sensors, Coin Cells and Energy Harvesters

By Microwave Product Digest, Cap XX Posted On 6.6.2019

Source: Microwave Product Digest article, Cap XX

by Pierre Mars, Vice President, Quality & Applications Engineering, CAP-XX (Australia) Pty Ltd

CAP-XX announced its 3V thin prismatic cells, suitable for slim form factor applications, that can be connected directly across a 3V battery. This has reduced cost and space and extends battery run time compared to placing a 2.7V regulator between the battery and a lower voltage conventional 2.7V supercapacitor. The article introduces the 3V supercapacitor’s characteristics and behaviour at the end applications. (more…)
