MF-1326B, F-291, Life Test No. 1 -- Initial Tests

Abstract

Pulse tests were performed on twenty-four Lot O, MF-1326B, F-291, ferrite cores preliminary to long-life tests. Cores of various disturbed one outputs as selected by the production tester were chosen for investigation. Measurements were made at several values of magneto-motive force between 1.0 and 1.5 ampere-turns. The maximum peak disturbed one was found to occur between 1.1 and 1.3 ampere-turns. Curves are plotted of the peak undisturbed one, peak disturbed one, peak disturbed zero, and disturbed zero at the time of peak disturbed one as well as the times associated with these outputs. The correlation between the peak undisturbed one and the core cross-sectional area are demonstrated.
