What are the characteristics of alloy resistors and ordinary resistors

Alloy resistors and ordinary resistors each have distinct characteristics, and the following is a detailed summary of their features:

Characteristics of alloy resistors:
High precision: Alloy resistors usually have extremely high precision, which can meet the demand for precise control of resistance values.
Low temperature coefficient: Alloy materials have excellent temperature stability, which makes the resistance value of alloy resistors change less with temperature, making them suitable for environments with large temperature changes.
High power: Alloy resistors can withstand high power and are suitable for high current and high voltage applications.
Long term stability: Alloy resistors can maintain stable resistance values during long-term operation and are not easily aged or deteriorated.
Corrosion resistance: Alloy materials typically have good corrosion resistance, allowing alloy resistors to maintain stable performance in harsh environments.
High reliability: The manufacturing process of alloy resistors is advanced and the quality is reliable, which can meet the requirements of high-precision and high reliability circuits.
Characteristics of ordinary resistors:
Low cost: The manufacturing cost of ordinary resistors is relatively low, suitable for large-scale production and application.
Diverse types: There are many types of ordinary resistors, including carbon film resistors, metal film resistors, wire wound resistors, etc., which are suitable for different application scenarios.
Widely applicable: Ordinary resistors are widely used in various electronic devices, such as power circuits, signal circuits, etc., to meet the needs of general circuits.
Ordinary performance: Compared to alloy resistors, ordinary resistors have relatively poor performance in terms of accuracy, temperature coefficient, power tolerance, etc., but they are sufficient to meet the needs of general circuits.
Easy to obtain: Ordinary resistors are easily available in the market and are relatively inexpensive, making them easy to repair and replace.
In summary, there are significant differences between alloy resistors and ordinary resistors in terms of accuracy, temperature coefficient, power bearing capacity, cost, type, and applicability. When selecting resistors, the appropriate type of resistor should be chosen according to the specific requirements of the application scenario.
