For partial qualification, testing to one particular inductance value shall be sufficient to grant qualificat
9、ion approval to any smaller inductance value than what was qualified. 2/ The inductance is measured with 0 A dc applied to (1-2) and at the specified voltage across (1-2). 3/ The amount of dc current that will reduce the inductance a maximum of 8 percent. REQUIREMENTS: (When numbers in parentheses,
10、such as (1-2) are used, they indicate the winding and the extreme terminals of the winding.) Electrical ratings: See table I. Design and construction: Dimensions and configuration: See figure 1. Duty cycle: Continuous. Case: Metal encased. Terminals: Solder terminal, ST-1708 or equivalent. Provided
