AN114 - High Voltage Ceramic Capacitor Testing Protocols

CalRamic Technologies provides High Voltage Capacitors for a variety of applications: Geothermal/Geophysical, Commercial and Military, Medical, and Hi-Reliability Space level.  A variety of environmental conditions exist in all of these applications, and understanding the Protocols and screening criteria can be a bit confusing.

The level of reliability associated with capacitor selection is generally dictated by the intended application in which a capacitor will be used and the associated environmental conditions to which the part will be subjected. These applications can differ significantly, from basic commercial applications, to more demanding industrial, military/aerospace or automotive programs, to system critical space applications. Ensuring that the chosen capacitor matches its intended application is critical to achieving long term success. This application note reviews the more
common applications and presents testing protocols most often associated with the governing specifications that exist.

Feel free to contact our Applications Engineering team to discuss the definitions and options to help find the correct part and screening for you.

Space Expo Europe 2017 Another Successful Event

Space Expo Europe 2017 was a huge success.  We would like to thank our distributor, Protech GmbH, for the fantastic booth space and hospitality.  It was a pleasure seeing old friends and having the opportunity to create new business relationships.  If you have any questions regarding our capacitor product lines you can contact CalRamic directly or one of our Sales Distributors serving your area.

AN106 - Partial Discharge Testing & Long Term Reliability

Most of us think of High-Reliability applications as limited to Spacecraft missions.  The fact is a non-repairable application can also be defined as high cost or limited access of the power supply.   Reliability of the high voltage capacitor being used in these type of applications is of the utmost importance.  CalRamic Technologies focuses on the proper designs, materials used, and strict processing of its components to ensure reliability.  Screening and testing for final inspection is vitally important to qualify the component.  

For high reliability applications, Partial Discharge Corona testing is a final screening test.  It is one of the most practical tests to detect minor and major defects in Ceramic Capacitors.   Application Note 106 outlines the general theory and screening criteria for High Voltage Ceramic Capacitors.
