Publish Time: 2024-10-30
Metal oxide film resistors are electronic components made by special processes with a wide range of resistance values, ranging from 1Ω to 200kΩ. The manufacturing process of this resistor is quite unique, mainly decomposing a hydrolyzed metal salt solution (such as tin tetrachloride, antimony trichloride, etc.) and covering the surface of hot glass or ceramics with deposits. This deposition process makes the resistor show many advantages in performance and characteristics.1. Unique manufacturing processThe manufacturing process of metal oxide film resistors embodies the perfect combination of technology and technology. By hydrolyzing and decomposing a specific metal salt solution and then depositing the resulting oxide on a carrier, a uniform and dense metal oxide film can be formed. This oxide film not only has excellent conductive properties, but also has a stable and reliable resistance value.2. Wide resistance rangeThe resistance range of metal oxide film resistors is wide, which can meet the needs of various circuits and applications. From a tiny 1Ω to a larger 200kΩ, this resistor can provide precise resistance control. This makes it widely used in a variety of electronic devices, such as communication equipment, computers, instruments, etc.3. Excellent high temperature resistanceA notable feature of metal oxide film resistors is their excellent high temperature resistance. Its operating temperature range is wide, from +140℃ to 235℃, and it can even be overloaded for a short time. This high temperature stability makes metal oxide film resistors perform well in applications under high temperature environments, such as industrial equipment, automotive electronics and other fields.4. Stable resistance temperature coefficientThe resistance temperature coefficient of metal oxide film resistors is small, usually within the range of ±3×10^-4/℃. This means that at different temperatures, its resistance value changes less, thus ensuring the stability and reliability of the circuit. This is especially important for circuits that require high-precision resistance values.5. Good chemical stabilityMetal oxide film resistors also have good chemical stability and can resist corrosion from a variety of chemicals. This allows it to maintain good performance in harsh environments, such as moisture, corrosive gases, etc.6. Limitations of resistance rangeAlthough metal oxide film resistors have many advantages, their resistance range is also subject to certain limitations. In particular, the resistance of low-power resistors usually does not exceed 100 kilo-ohms. This limits its use in certain applications with high resistance requirements to a certain extent. However, with the development of technology and the improvement of processes, this problem is expected to be solved.Metal oxide film resistors have been widely used in electronic devices due to their unique manufacturing process, wide resistance range, excellent high temperature resistance, stable resistance temperature coefficient and good chemical stability. With the continuous development of science and technology, metal oxide film resistors are expected to play their unique advantages in more fields.
