In particular, engineers need compact safety-certified components that support high-voltage operation and stringent insulation requirements.

As a result, Knowles recently released a new range of X1/Y2 safety-certified surface-mount multilayer ceramic capacitors (MLCCs).  [Read More](https://blog.knowlescapacitors.com/blog/introducing-a-new-line-of-high-performance-safety-certified-capacitors) 0 Comments [Click here to read/write comments](https://blog.knowlescapacitors.com/blog/introducing-a-new-line-of-high-performance-safety-certified-capacitors#comments-listing) Topics: [Capacitor](https://blog.knowlescapacitors.com/blog/tag/capacitor), [News and Events](https://blog.knowlescapacitors.com/blog/tag/news-and-events), [Electric Vehicles](https://blog.knowlescapacitors.com/blog/tag/electric-vehicles), [Industrial](https://blog.knowlescapacitors.com/blog/tag/industrial) ## [The Capabilities, Benefits, and Key Applications for StackiCap™ MLCCs](https://blog.knowlescapacitors.com/blog/the-capabilities-benefits-and-key-applications-for-stackicap) Posted by [Nan Zhang](https://blog.knowlescapacitors.com/blog/author/nan-zhang) on May 24, 2023, 8:30:00 AM - [Tweet](https://twitter.com/share) [![The Capabilities, Benefits, and Key Applications for StackiCap](https://blog.knowlescapacitors.com/hubfs/StackiCap%20Capacitor.png)](https://blog.knowlescapacitors.com/blog/the-capabilities-benefits-and-key-applications-for-stackicap) From industrial to automotive to aerospace applications, power electronics are demanding higher capacitance in smaller packages. Therefore, to meet both capacitance demands and size requirements, electronic designers simply cannot continue to add more capacitors. While capacitor stacking is an option, many stacked assemblies are still quite large and stacking often introduces new failure modes, such as piezo electric cracking (Figure 1).  [Read More](https://blog.knowlescapacitors.com/blog/the-capabilities-benefits-and-key-applications-for-stackicap) 0 Comments [Click here to read/write comments](https://blog.knowlescapacitors.com/blog/the-capabilities-benefits-and-key-applications-for-stackicap#comments-listing) Topics: [Capacitor](https://blog.knowlescapacitors.com/blog/tag/capacitor) ## [Supporting EV Battery Innovation with the Highest Voltage AEC-Q200 MLCCs](https://blog.knowlescapacitors.com/blog/supporting-ev-battery-innovation) Posted by [Nan Zhang](https://blog.knowlescapacitors.com/blog/author/nan-zhang) on Jun 17, 2020, 6:00:00 AM - [Tweet](https://twitter.com/share) [![](https://blog.knowlescapacitors.com/hubfs/capacitors%20low%20res.jpg)](https://blog.knowlescapacitors.com/blog/supporting-ev-battery-innovation) To meet consumer demand for longer driving ranges and faster charging, electric vehicle (EV) manufacturers are redesigning vehicles to move from 400V to 800V battery systems. As a result of using higher operating voltages, EV designers and original equipment manufacturers (OEMs) need components, such as multi-layer ceramic capacitors (MLCCs), that can withstand voltages well beyond those expected under normal operating conditions. For example, a drivetrain running off an 800V battery system may be subjected to a withstand test of up to 4kV DC for 60 seconds, which is a standard safety test in high voltage systems.
