The SQ-SEN-1TR appears to be a surface mount current sense resistor. Current sense resistors are used to measure current flow in a circuit by measuring the voltage drop across the resistor. The resistance value is low, allowing for minimal impact on the circuit's performance while still providing a measurable voltage signal proportional to the current.
