MIL-STD-1553 Transformers
Low Profile SMT Dual non-QPL Interface Transformers
These non-QPL interface transformers are built and tested in ISO 9001 approved facilities. They
conform to all electrical and physical parameters of MIL-PRF-21038/27. Choose one of three
operating temperature ranges including 0° to +70°C, -40° to +85°C, or -55° to +125°C.
