Technology: Advantages And Disadvantages Detailed Analysis Of Typical Application Resistors

Apr 01, 2016

For nearly 20 years, the electronics industry is developing at an alarming rate. Progress in reducing the size of the new technology at the same time, increases pressure on discrete component device manufacturers to develop the ideal performance.

In these devices, the chip resistor current demand remains very high, and is the basis of many circuit components. Their space utilization over discrete package resistance, reducing the workload of the Assembly preparation. With the popularity of applications, chip resistor has an increasingly important role. Main parameters includes ESD protection, thermal EMF (EMF), the thermal coefficient of resistance (TCR), since the coefficients of thermal resistance, long-term stability, power and noise.

Wire wound resistor will be discussed in the following technology comparison application in precision circuit. However, please note, wirewound resistors have no chip, therefore, the weight and size limits require application of precision chip resistors do not use this kind of resistance.

Although upgrading can improve the overall performance of each component or subsystem, but overall performance is determined by the short Board components in the chain. Each component in the system has inherent advantages and disadvantages related to overall performance, especially in the short term and long term stability, frequency response and noise issues. Discrete online winding resistance, resistance thick film resistors and resistance and metal foil resistor technology has made progress, while unit costs, each resistor has many factors to be weighed.
