CTS Expands Current Sensing Resistor Product Line
Lisle, IL – CTS Corporation (NYSE: CTS) has announced a major expansion to its Current Sensing Resistor portfolio. New designs providing lower resistance values down to 0.25 milliohms, increased power ratings up to 5 Watts and more standard EIA package sizes are now available.
Current sensing resistors are used in electronic systems to monitor the flow of current by translating into a voltage that is easily measured and controlled by a current sense amplifier circuit. This is a key aspect in power and instrumentation applications for circuit control, monitoring and protection.
Today’s current sensing resistors provide the designer with simple low cost solutions, smaller resistance values that minimize power loss, lower parasitic inductances for improved frequency characteristics and small package footprints. These have become very important factors in the rapidly growing use of battery powered electronic devices.
