Modbus Products

TDK offers a wide range of components ideal for the design and development of Modbus circuits. Modbus is the standard serial communication protocol used throughout many industries to transmit and collect data from one electronic device to another. The Modbus protocol is commonly used in the design of the Industrial Internet of Things (IIoT). TDK components for Modbus-related applications feature a wide range of general passive devices such as signal inductors, common-mode filters, signal transformers, inductors, chokes, aluminum electrolytic capacitors, SMD varistors, and surge arresters. A full range of sensors and sensor systems are available for specific Modbus sensor requirements.
