Precision Resistance Comparison Table HD Complete Collection - One Stop Reference for Precision Electronic Components

In today's rapidly changing technology, precision resistors play a crucial role as an important component of electronic components. However, for beginners and professionals, understanding and selecting the appropriate precision resistors is not an easy task. In order to help everyone better grasp this knowledge, we have specially created this high-definition collection of precision resistance comparison tables

1、 What is a precision resistor

Precision resistor, as the name suggests, is a type of resistor with extremely high precision. Its resistance can vary within a very small range, and the resolution can reach one in millions (0.001%) or even higher. The manufacturing process of this type of resistor is extremely complex and requires high-precision equipment and technology, so the price is relatively high

2、 The main parameters of precision resistors

Resistance range: This is the basic property of precision resistors, representing the ratio between the maximum and minimum voltage they can withstand. Common resistance ranges include 1 Ω, 10 Ω, 100 Ω, etc

Accuracy level: This is an important parameter for measuring the accuracy of precision resistors, usually expressed as a percentage. For example, a 1% accuracy means that in actual use, the resistance change of a precision resistor does not exceed 1% of its nominal resistance value

Power: This is the maximum power that a precision resistor can withstand, usually measured in milliwatts (mW). The higher the power, the more demanding the working environment that precision resistors can withstand

Working temperature range: This is the highest and lowest temperature that precision resistors can withstand under normal working conditions. Generally speaking, the wider the operating temperature range, the more applications precision resistors have

3、 How to choose a precision resistor

Choose according to circuit requirements: Firstly, you need to understand what kind of precision resistors your circuit requires. For example, if your circuit requires high precision, you should choose a precision resistor with a higher level of accuracy

Consider power requirements: Secondly, you need to consider the power requirements of your circuit for precision resistors. If your circuit power is high, then you need to choose a precision resistor with higher power

Consider environmental factors: Finally, you need to consider the working environment factors of precision resistors. For example, if your circuit operates in a high-temperature environment, you need to choose a precision resistor that can work at high temperatures
