MIL-STD-1553 TRANSFORMERS ( US )
GJB289A-97 TRANSFORMERS ( CHINA )
MADE IN CHINA
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.
