Achieves impedance matching, prevents signal reflection, and improves signal integrity

RIVERSIDE, Calif. – May 8, 2025 – Bourns, a leading manufacturer of electronic components for power, protection and sensing solutions, today announced that its SSD Digital Current Sensor series is now available with an internal 120Ω resistor option in both CANbus and RS-485 versions. This new option gives designers the benefit of additional impedance matching and anti-signal reflection, helping to ensure robust communications. Using Bourns® SSD Digital Current Sensors with the resistor option helps maintain signal integrity and prevent communication errors, especially over long distances and high speeds.

Bourns® SSD digital current sensors offer superior accuracy, stability and electrical isolation over a wide operating temperature range (-40°C to +115°C), even in harsh industrial and automotive environments. The series features 1500 VDC reinforced galvanic isolation, a 16-bit +150°C microcontroller, a 24-bit ADC with buffered analog inputs and ECC flash memory with auto-correcting single-bit error capability. These advanced features make them an ideal solution for battery systems, renewable energy, motor drives and EV charging stations.

A new internal 120 Ω termination resistor option is integrated into the sensor's PCB and is now available in rated current values of 100 A, 250 A and 500 A. The Bourns® SSD Digital Current Sensor series is RoHS compliant.
