適用范圍：1.1 This standard (Part IV) lays down the tests and requirements for pulse and switching transformers intended for use in electronic equipment.1.2 The following transformers are covered by this standard:a) Pulse transformers such as those used:1) in blocking oscillator applications;2) as isolation/coupling transformers;3) in thyristor triggering applications, etc; and4) in radar transmitters and similar equipments.b) Switching transformers for transistor converter/inverter circuits.1.3 The types not covered are the distinctly non-linear pulse transformers and inductors and magnetic amplifiers used in special applications such as:a) those used in pulse forming networks, ferroresonant constant voltage transformer, magnetic pulse modulators, pulse magnetic amplifiers, magnetic frequency multipliers and dividers; andb) those used in memory ( storage) shift register, counting, switching and logic circuits.
