Resistive selection guide: common resistance characteristics and advantages and disadvantages

The electronics industry has developed at an alarming rate in the past 20 years. The development of new technology reduces the size of the equipment and also increases the pressure of discrete component manufacturers to develop ideal performance devices.

In these devices, chip resistors are currently in high demand and are the basis of many circuits. Their space utilization ratio is superior to that of the vertical packaging resistor, which reduces the work load of pre-assembly preparation. With the popularization of the application, chip resistors play an increasingly important role. The main parameters include ESD protection, thermal electromotive force (EMF), resistance thermal coefficient (TCR), thermodynamic, long-term stability, power coefficient and noise.

The following technical comparison will discuss the application of wire wound resistance in precision circuit. Note, however, that the wire wound resistance has no chip type, so the use of precision chip resistors is not used by weight and size constraints.

While upgrading each component or subsystem can improve overall performance, the overall performance is still determined by the short board in the component chain. Each component in the system has inherent advantages and disadvantages to overall performance, especially short-term and long-term stability, frequency noise and noise. Discrete resistor industry online wound resistors, thick film resistor, thin film resistance and metal foil resistance technology progress, and performance from the unit cost considerations, each resistance there are many factors need to be weighed.
