Resistors, passive devices made using different materials, are electrical components that help control the flow of current in a circuit and applicable to a broad range of applications, including FA and robot.
 
In the industrial world, especially in the field of FA, the integration with IT such as "Industry 4.0" and "Industrial-Internet" and the use of big data are attracting attention. In particular, there are an increasing number of cases where high precision resistors are used for signal processing of many sensors of IoT.

 
In addition, the number of small motor used is increasing due to multi-joint and multi-axisization in industrial robots and extension of service robots. A low resistor for current detection is used for this motor control. Metal thin film chip resistors, metal foil resistor ( like Microhm MPR series ), metal film resistors, high power resistors, networks are utilized in power supply unit, joint part and tip portion frequently.

 
In high-speed switching devices such as IGBTs and SiC-MOSFETs, there is a need for small high-power resistors as a countermeasure against transient currents.
