USA and International University Research Support with CalRamic Capacitors

As the Fall semester nears in the Northern Hemisphere CalRamic Technologies LLC extends an offer to supply free high voltage ceramic capacitors for University research and development.  We support National and International University power supply research that impact all industries.  Students and professors can request the ceramic capacitor samples to help promote ongoing studies and technology.

Testing / Screening Requirements

Ceramic capacitors are considered to be highly reliable, effective components, which offer a number of advantages compared to other capacitor technologies and as such are often employed in a wide variety of extremely demanding applications. That said, like all manufacturing environments, there tends to be a certain amount of variation inherent to the process that will result in differences in the performance characteristics of each device. In truth, even though a lot of capacitors may have been manufactured at precisely the same time, using the same batch of material, tooling and equipment, no two capacitors within that lot are “exactly” the same. Fortunately their differences tend to be inconsequential and certainly well within the acceptable limits of the system or application for which they are intended.

So if manufacturing operations for ceramic capacitors tend to produce highly consistent results, why test at all? There are in fact several reasons, not the least of which would be to ensure that the theoretical design meets customer expectations. In addition, it is important to ensure that some unintended process variable has not inadvertently been introduced to the system, which could alter the anticipated result. Testing also provides confirmation that the materials used to manufacture the capacitor are within specification and that the equipment will operate properly.

HV Ceramic Capacitors for X-Ray and Diagnostic Applications

High voltage ceramic capacitors are necessary for high frequency purposes like x-ray and diagnostic applications.  X-Ray processes can range from bomb detection to bone densitometry.  The high voltage ceramic capacitors manufactured by CalRamic provide the required high reliability and superior performance for these applications.

One such diagnostic application example, shown below, is the Gamma Camera.  The device is used to image gamma radiation emitting isotopes that are injected or inhaled into the patient.  Flat crystal planes are coupled into an optical array that counts the gamma photons absorbed by the crystals.  Two-dimensional images are created from the captured gamma radiation.  This imaging technique is used to scan the brain, thyroid, lungs, liver, gallbladder, kidneys and skeleton.  Unlike conventional x-ray techniques that scan structure and anatomy, the gamma camera produces imagery that maps the function and processes of the body.

HV disc low loss capacitors (CRT-0019), along with the HV disc capacitors (CRT-0006) and the HV multilayer capacitors (CRT-0010), manufactured by CalRamic, would provide the capacitance necessary for successful application in the X-Ray/diagnostic industry.  These capacitors are manufactured under strict quality control guidelines to ensure unparalleled performance in high voltage applications.
