Features of other interface chips:

The resistance value of precision wire wound resistor can range from a few tenths of a ohm to tens of megohm, and the accuracy can reach more than 0.01%. The temperature coefficient of the resistance can be less than 10ppm/K, and the long-term stability of the resistance can be less than 0.005%/ year. The disadvantage is that the high frequency performance is poor, but the non-inductive winding method can be fully improved.

Precision winding resistor package:

other interface chips are generally divided into glass epoxy steel pipe seal, aluminum shell seal and plastic shell seal according to the sealing method.

What are the advantages and disadvantages of wire-wound resistors?

The wire-wound resistor is made of nickel-chromium wire, manganese copper wire, constantan wire wrapped in a porcelain tube, which is divided into fixed type and adjustable type.

The advantages of high-power wire-wound resistor are: high precision resistance, low noise, stable and reliable operation, small temperature coefficient, high temperature resistance, and can still work normally at 170 ambient temperature.

Disadvantages of wire-wound resistance: large volume, low resistance value, mostly below 100K. In addition, due to structural reasons, its distributed capacitance and inductance are relatively large, so it can not be used in high-frequency circuits. Because the resistance of the winding acts as a choke on the current, the current is not easy to pass through.

Through the introduction of other interface chips, we understand the related content of wire-wound resistance. There are now a variety of high-precision, low-noise winding resistors. We can choose the right one and use it for a long time.
