How to choose Guangjie precision alloy resistor?

Photoresist: how do we choose photoresist precision alloy resistor? What are the precautions for use?

Photoresist precision alloy resistor is a kind of photoresist, which is widely used in our life. Do you know how to choose Guangjie precision alloy resistor? Next, the precision resistor manufacturer will teach you some methods to select optojie precision alloy resistors.



Resistor manufacturers remind you that temperature drift is the main factor determining the price of precision resistors. The four pin structure is conducive to accurate sampling, which is generally used in current detection. Only in this way can we reduce the surface temperature of the resistance and improve the stability of the sampling resistance, use a larger size or reserve more power space and increase the auxiliary radiator.

Resistor manufacturers remind you that resistors are usually used in power systems, such as resistance transformers, which usually require secondary packaging. Therefore, the surface of the resistor package must be smooth and match with the secondary packaging material. Otherwise, a small gap may be formed between the resistor surface and the packaging material, thus carbonizing the packaging material.

Resistor manufacturers mainly use film and foil technology to produce Guangjie precision alloy resistors. Among them, the foil resistance has better electrical performance, which can almost achieve zero temperature drift and 0.001% accuracy. Therefore, compared with other types of chip resistors, it has excellent characteristics and obvious advantages. It is considered to be a product close to the ideal resistance.

So what should we pay attention to when using precision resistors? Let's take a look at the precautions for using Guangjie precision alloy resistor.

The resistance adopts cap structure, axial lead, coated with insulating paint, direct reading word mark or color ring mark. The resistance index is similar to that of precision film. Crystal precision resistance has the trend of being replaced by chip precision film resistance, but pin precision resistance is still the mainstream of low-cost precision resistance technology.

The use of resistors should pay attention to the packaging of resistors. Packaging is an intuiive parameter of resistance, as you can see. Common resistance packaging includes on-line packaging and surface mount packaging. They have different shapes due to power, process and other reasons.

If a load exceeding the rated power of the precision resistor is applied in a short time, it must be confirmed in advance whether the resistor has the ability to resist short-term impact. In order to prevent the fatigue of the alloy wire of the precision resistor, please use the load of the resistor within the specified power curve of the resistor.

To sum up, the precautions for using precision resistors are introduced. When using Guangjie precision alloy resistor, attention must be paid to avoid improper use, which will affect the use effect of precision resistor.
