CONNECTORIZED DUAL STUB DATA
BUS COUPLER
- DBC 1002
Compupower provides Connectorized Data Bus Couplers with Single, Dual, Four and Six Stubs. These Couplers are available with and without internal terminations.
All resistors are 1Watt per MIL-R-39007 and mounted away from the transformer to minimize heating effects. The transformers are manufactured to MIL-T-21038.
All Couplers are 100% tested and certified.
Features:
- 1Watt Isolation resistors
- 1Watt Terminating resistors
- -55°C to +125°C operating temperature.
Benefits:
- Qualified and type approved for flight applications
- Low cost
- Highly reliable
- Bast delivery
