High Temperature Properties of Solid Tantalum Chip Capacitors

The use of tantalum chip capacitors in conjunction with hybrid circuitry requires stable capacitor characteristics that will withstand the stresses of component attachment, testing, and circuit operations. A line of miniature tantalum chip capacitors is discussed with emphasis on materials, constructional methods, and resultant performance of the devices under environmental and operational conditions. Results of exposure to high temperature attachment conditions are presented with details of impedance and dissipation factor characteristics as well as other traditional capacitor parameters.
