Revealing the difference between alloy resistance and thick film resistance

With the continuous development of electronic technology, resistors are playing an increasingly important role in various electronic devices. Among many types of resistors, alloy resistors and thick film resistors are two common types of resistors. Although they have many similarities in functionality, there are still some obvious differences between them. This article will provide you with a detailed introduction to the differences between alloy resistors and thick film resistors

Differences in Manufacturing Processes of Alloy Resistors

1 Alloy resistance

Alloy resistor is a type of resistor made of metal material as the resistance material. Its production processes mainly include powder metallurgy, electrolysis, and vacuum evaporation. The manufacturing process of alloy resistors is relatively complex, requiring precise control of material composition and production process parameters to ensure the performance and stability of resistors

2 Thick film resistor

Thick film resistor is a type of resistor made using thin film technology. Its production process mainly involves printing, coating, and hot pressing to deposit the resistive material on the substrate, forming a layer of resistive film with a specific thickness. The manufacturing process of thick film resistors is relatively simple, cost-effective, and can achieve high accuracy and stability

Differences in performance characteristics of alloy resistors

1 Alloy resistance

The main characteristic of alloy resistance is its wide range of resistance values, which can accommodate more resistance lines in a smaller volume, thereby reducing volume and weight. In addition, alloy resistors also have good oxidation resistance and moisture resistance, making them suitable for use in harsh environmental conditions. However, the temperature coefficient of alloy resistance is relatively large, and its resistance value will change when the temperature changes, which may affect the performance of the circuit

2 Thick film resistor

The main characteristics of thick film resistors are their high accuracy, stable resistance values, and small temperature coefficients. Due to its simple manufacturing process and low cost, thick film resistors are widely used in the market. However, the resistance range of thick film resistors is relatively narrow and easily affected by environmental factors such as humidity, temperature, etc., resulting in significant changes in their resistance values

Differences in Application Fields of Alloy Resistors

1 Alloy resistance

Alloy resistors are widely used in fields such as communication, computers, automotive electronics, and household appliances. Due to its wide resistance range and good stability, alloy resistors are widely used in various high-precision electronic products

2 Thick film resistor

Thick film resistors are mainly used in fields such as home appliances, lighting, and security. Due to its low cost and high accuracy, thick film resistors have a wide range of applications in these fields

Although alloy resistors and thick film resistors have many similarities in functionality, they still have certain differences in manufacturing processes, performance characteristics, and application fields. Understanding these differences helps us choose suitable resistors in practical applications to meet the various needs of electronic devices
