Abstract:

The processing and assembly of two groups of engineering samples 200 starts each has been done with a very minimum of mechanical losses and indicates that no mechanical modifications of the capacitor design will be required for future manufacturing. The test data compiled on Group I Engineering Samples and on several lots of evaluation samples, resulted in process changes for Group II Engineering Samples, which gave improved DF and insertion loss characteristics over the Group I Engineering Samples. The dip in insertion loss above 100 Mc appears to be characteristic of the feedthrough capacitor design. Evaluation tests on purchased anodes indicate that they are acceptable and it is planned to use them in the preproduction samples. Life test failures on both groups of engineering samples indicate that prolonged low impedance aging may be necessary to screen out those units which might be capable of passing a life test in very low impedance circuits such as directly off of batteries.
