3rd edition of the PCNS Passive Components Networking Days Symposium is hosted by Department of Chemistry, Materials and Chemical Engineering “Giulio Natta” and Department of Electronics, Information and Bioengineering Faculty of Politecnico di Milano.
Electrochemical capacitors (ECs) have only recently been considered as an alternative power source for telemetry sensors of drilling equipment for geothermal or oil and gas exploration. The lifecycle analysis and modeling of ECs are underrepresented in literature in comparison to other storage devices e.g. Li-ion batteries.
Multilayer ceramic capacitors are placed near IC devices mounted in a smartphone or wearable device for the purpose of decoupling. With the trend toward thinner devices, improved functionality, and larger battery size, the mounting area available for parts is shrinking. There is a need for increasing the mounting density, such as mounting low-profile parts at the back of the IC package, rather than the conventional method of mounting parts on the substrate.
This new semiconductor process will be the foundation of a new high voltage capacitor product line,” said Stephen G. Daly, President, and Chief Executive Officer. “We recognize many automotive, renewable energy, industrial, medical, and defense systems operate at high voltages. Our technology is capable of enabling non-commodity applications in these markets where smaller size and superior electrical performance over standard industry capacitors is desired.”
Vishay Intertechnology introduces a new series of metalized polypropylene AC filtering film capacitors optimized for high humidity environments.
Vishay Roederstein MKP1847C AC Filtering devices withstand demanding temperature humidity bias (THB) testing —40C, 93 % relative humidity for 56 days at rated voltage —without altering their electrical characteristics.
The 381-383LL aluminium electrolytic snap-in series, designated with an expected life of 8,000 hours at full-rated conditions, demonstrates superb stability in capacitance and DC leakage current overtime on a test. The snap-in series is targeted for use in critical applications where long life and reliability are paramount.
The supply of aluminum electrolytic capacitors is expected to remain tight throughout the first half of 2021, thanks to strong demand for servers, power supply, automotive electronics, and 5G infrastructure applications, according to industry sources in Taiwan.
A switched-capacitor circuit is a discrete-time circuit that exploits the charge transfer in and out of a capacitor as controlled by switches. The switching activity is generally controlled by well-defined, non-overlapping clocks such that the charge transfer in and out is well defined and deterministic.
MKP3386 Y2 EMI suppression film capacitor has also been shown to withstand case temperatures of +125 °C at up to 500 h of continuous operation.Details about the product’s specifications can be seen on datasheet. For even higher humidity robustness for Y2 applications
