However, at very high frequencies, the ideal behavior of a capacitor can be compromised. In those situations, the parasitic, resistive and inductive components of a capacitor have an outsized influence on its behavior.  [Read More](https://blog.knowlescapacitors.com/blog/role-of-resonant-capacitors-in-power-electronics) 0 Comments [Click here to read/write comments](https://blog.knowlescapacitors.com/blog/role-of-resonant-capacitors-in-power-electronics#comments-listing) Topics: [Capacitor](https://blog.knowlescapacitors.com/blog/tag/capacitor) ## [Capacitor Fundamentals: Part 12 – Visual Standards for Chip Capacitors](https://blog.knowlescapacitors.com/blog/capacitor-fundamentals-part-12-visual-standards-for-chip-capacitors) Posted by [Simon Mao](https://blog.knowlescapacitors.com/blog/author/simon-mao) on Oct 7, 2023, 8:15:00 AM - [Tweet](https://twitter.com/share) [![Capacitor Fundamentals Blog Series\_Blog 12](https://blog.knowlescapacitors.com/hubfs/Capacitor%20Fundamentals%20Blog%20Series_Blog%2012.png)](https://blog.knowlescapacitors.com/blog/capacitor-fundamentals-part-12-visual-standards-for-chip-capacitors)   Welcome to the [Capacitor Fundamentals Series](https://info.knowlescapacitors.com/knowles-precision-devices-capacitor-basics), where we teach you about the ins and outs of chips capacitors – their properties, product classifications, test standards, and use cases – in order to help you make informed decisions about the right capacitors for your specific applications.

The primary function of the DC link is to store energy during the times when the input power is higher than the output power and release energy when the output power demand exceeds the input power. The DC link should include a capacitor that servers as a supporting filter to act as a buffer, minimize voltage ripples, and smooth and stabilize the power flow between various components such as rectifiers, inverters, and other converters in the power system.

In other words, Q factor tells us how good a capacitor is at its job at a certain frequency. A high Q value indicates low energy loss during operation, making these capacitors a good fit for applications requiring low power dissipation and high stability.   [Read More](https://blog.knowlescapacitors.com/blog/high-q-capacitors-roles-and-specifications) 0 Comments [Click here to read/write comments](https://blog.knowlescapacitors.com/blog/high-q-capacitors-roles-and-specifications#comments-listing) Topics: [Capacitor](https://blog.knowlescapacitors.com/blog/tag/capacitor) [Previous](https://blog.knowlescapacitors.com/blog/tag/capacitor/page/8) [All posts](https://blog.knowlescapacitors.com/blog/all) [Next](https://blog.knowlescapacitors.com/blog/tag/capacitor/page/10) ## Insights Into Precision Passive Devices Knowles Precision Devices is a premier global source for Capacitors, RF Filters, EMI Filters, Resonators, non-magnetic components and advanced dielectric materials.
