DESCRIPTION AND APPLICATIONS The military data bus specification, MIL-STD-1553, has brought about the need for versatile pulse transformers that meet all the electrical requirements of Manchester II serial biphase data transmission. Our var- ious package styles provide the turns ratio configurations, component isolation, and common-mode rejection ratio characteristics necessary for MIL-STD-1553A and B compliance(CHINA GJB289A-97). Hermetically sealed or epoxy cased, these transformers are mulitapp- ed to accommodate existing system configurations.Encapsulated in accordance with MIL-PRF-21038, their tin-coated, copper-clad steel leads (epoxy-cased units) conveniently accommodate printed circuit board mounting. Sinusoidal or trapezoidal waveforms are accurately processed, making these transformers an excellent choice for any MIL-STD-1553A or B application.
