A Custom Approach to Large Capacitor Assembly

Posted by Steve Hopwood on Oct 13, 2021 9:00:00 AM

Achieving high capacitance means going big. But how do you do that while still maximizing board space? At Knowles Precision Devices, we’ve developed a new method for building customizable large capacitor assemblies that capitalize on the vertical space above the circuit board. While stacked capacitor assemblies have been around for many years, these parts do not have very good bump and vibration withstand due to the thin leads used in their construction. These new assemblies from Knowles Precision Devices offer a ruggedized construction capable of withstanding high levels of shock and vibration. This offers a unique combination of capability, durability, high capacitance, and very high voltage in a smaller area, making these capacitors ideal for automotive, military, and aerospace applications.

Solving Tough Technical Challenges Through Agility and Experience

Posted by Steve Hopwood on Sep 8, 2021 9:00:00 AM

At Knowles Precision Devices, we thrive on working with companies who want to take technically challenging ideas and work through the details to figure out how to turn their seemingly impossible ideas into reality. This is because we are not limited to volume production and have extensive experience making specialty and custom parts. We are also familiar with the challenges associated with delivering high-reliability components as we supply many industries and applications that depend on the consistent functionality of custom-shaped parts. For example, we provide numerous space grade components and we are the only manufacturer who has developed planar array ceramic parts for the International Space Station.

Meet Safety Requirements at Higher Voltages with New Safety-Certified MLCCs

Posted by Steve Hopwood on Mar 17, 2021 7:00:00 AM

With our new expanded range of enhanced safety-certified multilayer ceramic capacitors (MLCCs), Knowles Precision Devices now offers a unique combination of capability and safety certification for electronic device applications. These new surface-mount MLCCs comply with international UL60384-14 and EN60384-14 specifications and can be used instead of leaded film capacitors in AC-DC power supplies where a lightning strike or other voltage transients represent a threat to the electronic equipment.

Understanding the Impact of ESR on Ceramic Capacitor Selection

Posted by Victor Lu on Mar 10, 2021 7:00:00 AM

In an ideal world, capacitors could be designed in a way where they would exhibit no resistance. However, this is physically impossible to achieve as there will always be some type of internal resistance in a capacitor that appears in series with the capacitance of the device. Known as equivalent series resistance (ESR), the level of this resistance will vary across capacitors depending on a variety of factors including the dielectric materials used, frequency of the application, leakage, and quality and reliability of the capacitor. The two graphs in Figure 1 show an example of how ESR can change as frequency increases across various capacitances on two different classes of ceramic dielectrics.

New SV Series Capacitor Assemblies: The Perfect Fit for Power Supply Filtering

Posted by Daniel Callen on Jul 22, 2020 8:30:00 AM

In general, a capacitor assembly attaches multiple capacitors together into a single subassembly. This approach results in increased electrical performance such as higher voltages, higher capacitance, or higher power, while also simplifying manufacturing assembly and providing a significant reduction in board space needed.
