What is metal oxide film resistance?

Metal oxide resistors, also known as metal film resistors or metal oxide film resistors, are electronic components that use metal oxides as resistance materials. This type of resistor is made by depositing a layer of metal oxide film on a ceramic rod or tube, and then sintering, adjusting the resistance value, and other processes.

The main characteristics of metal oxide resistors include:

Good stability: Due to the stable chemical properties of metal oxide materials, this resistor has excellent stability and its resistance value is not easily affected by environmental factors such as temperature and humidity.
High precision: Metal oxide resistors have a wide range of resistance values and can achieve high-precision resistance values by adjusting process parameters.
Large power range: This resistor can be made into different power specifications to meet the needs of different circuits.
Good high-frequency characteristics: Metal oxide resistors have excellent high-frequency characteristics and are suitable for high-frequency circuits.
In addition, metal oxide resistors also have good heat shock resistance and moisture resistance, and can maintain stable performance in harsh environments.

In electronic circuits, metal oxide resistors are widely used in various applications, such as current limiting, voltage divider, shunt, load, matching, filtering, oscillation, pulse and other circuits. Its excellent performance and wide range of applications make it an indispensable and important component in the electronics industry.

Overall, metal oxide resistors are stable and high-precision electronic components, and their manufacturing process and performance characteristics make them an important component of electronic circuits.
