Abstract : Efforts were directed toward a production engineering measure for subminiature temperature compensating ceramic capacitors. The temperature coefficient of capacitance (TC) requirement for the NP0 capacitors was achieved as a result of work during this period. A recapitulation of areas investigated in the study leading to this attainment is presented herein. Approval of the Case Size III qualification samples was received, and pilot production on the three formulations of this case size will begin as soon as authoriza on is received. The status of pilot production for Case Sizes I and II is given in this report.
