KOA resistors provide a broad space for selection with rich types and excellent performance, although brand awareness and product quality are more popular, but the selection should also pay attention to many matters.
The selection process needs to fully consider the working environment and performance requirements of the circuit. For example, circuits that work in high temperature, high humidity or corrosive gas environments should choose the anti-vulcanization chip resistor series to ensure the stability and reliability of the resistor. In the case of extremely high resistance accuracy requirements, such as precision measuring instruments or medical equipment, it is appropriate to choose the film type resistor series to meet the needs of high-precision measurement.
For high-power circuits or occasions that require long-term stable work, resistors with high power tolerance and good heat dissipation performance should be selected, such as moulded chip resistors or cylindrical resistors, which can effectively avoid performance degradation or damage caused by overheating.
In addition, according to the rated current and overload capacity of the circuit to choose the appropriate fuse resistor model and specification, fuse resistor can automatically fuse when there is overcurrent or short circuit in the circuit, so as to protect other components from damage, in the selection of network rejection series and jumper resistor series, also need to be considered in combination with actual needs. The network exclusion series is suitable for applications where multiple resistance values are required to simplify circuit design and improve integration. The jumper resistor series provides a flexible resistance adjustment method to facilitate resistance adjustment during circuit debugging and troubleshooting.
