Bosch Ground Loop Isolation Transformer
TC8235GIT Key Features
• Ground isolation for 75 Ohm video/data lines
• 10 Hz to 7 MHz bandwidth
• Low insertion loss
• Insulated BNC connectors
• Excellent discrimination against power line interground potentials
TC8235GIT Description
The TC8235GIT is a one-to-one isolation transformer for 75 Ohm coax video/data lines. These units are designed to eliminate the effects of power line and spurious noise potentials between ground points on transmitted signals.
