New KEMET DC-Link Power Box and Resonant Film Capacitors for High Temperature in Industrial and Automotive Applications

Full paper pdf download Downsizing and footprint reduction are constant requirements of the market for all applications or equipment and the relative components. Film capacitors are not an exception and time by time is required to reduce the components dimension maintaining the same rated voltage and performances. Decreasing the volume of the components, one of the consequences is a reduction of the power dissipation...

Class II MLCCs – More Detailed Classification or More Specific Default Parameters?

Class II MLCCs – More Detailed Classification or More Specific Default Parameters?

Full paper pdf download Some of the “standard” parameters provided by the producers are not relevant in case of class II MLCCs. For these devices the designer must perform additional calculations and tests to select and to validate a class II MLCC for an application with given requirements. Variation of the main parameter (capacitance) due to usage conditions is so large that it behaves...

Class-II MLCC DC-Bias Aging Issues in Automotive Application

Class-II MLCC DC-Bias Aging Issues in Automotive Application

An update on what has been going on at Continental Automotive since we got to know this Phenomenon. Full paper pdf download The trend in our technology is always towards higher power density and miniaturization. We know that this brings not only advantages like space and cost savings but can also entail disadvantages – sometimes even unexpected behavior. We at Continental have been faced...

Screening and Qualification of BME Feedthrough Capacitors for a Space Project

Screening and Qualification of BME Feedthrough Capacitors for a Space Project

Full paper pdf download Surface mount technology feedthrough ceramic capacitors are gaining popularity in Hi-Rel systems due to small size and great filtering characteristics.  In this work, BME feedthrough capacitors compliant with AEC-Q200 requirements have been evaluated, screened and qualified for a space project.  Evaluation included analysis of the effect of post-soldering thermal shocks, temperature dependencies of leakage currents, distribution of breakdown voltages, assessments...

Overcoming the Challenges of Using Sub-Milliohm SMD Chip Resistors

Overcoming the Challenges of Using Sub-Milliohm SMD Chip Resistors

This paper was presented by Stephen Oxley, TT Electronics at the 3rd PCNS 7-10th September 2021, Milano, Italy as paper No.3.1. and voted by attendees as: OUTSTANDING PAPER AWARD The most cost effective and simplest way of converting a measured current to a voltage signal is to use a low ohmic value current sense resistor. The increase in products containing batteries, motors or actuators...
