Cryogenic Capacitors for Low-Temperature Power Systems, Phase I

TRS Technologies proposes to develop low-temperature multilayer ceramic capacitors (MLCCs) capable of operating at cyrogenic temperatures (<77K). These capacitors will be based upon quantum paraelectrics and relaxor ferroelectrics. The MLCCs will have high volumetric efficiencies, low dielectric losses, and a reduced temperature coefficient of capacitance. In the Phase I program TRS will fabricate MLCCs that operate at or below 77K and will demonstrate their feasibility for cryogenic capacitors by characterizing the dielectric properties (capacitance, loss, insulation resistance, breakdown strength, etc.) at temperature from 12K to 300K.
