Thick acoustic thick film resistor is a kind of resistor with thick film resistance layer on ceramic substrate, which is characterized in that the thickness of the resistance layer is much larger than that of the thin film resistor. Compared with thin film resistors, thick film resistors differ in manufacturing process and performance, for example, thick film resistors are 1000 times thicker than thin film resistors. Thick Sound Group is a research and development and production of resistance manufacturers, the main products include thick film patch resistor, film patch resistor and so on. Thick sound conventional thick film resistor is widely used in medical equipment, testing equipment, mobile phone, GPS, PDA, communication equipment, automation equipment, printing equipment, frequency converter and other industries because of its wide application range, cheap price and suitable for automatic assembly.
Although the thick film resistor is difficult to achieve high-precision low-temperature bleaching and noise indicators in the low resistance part, the long-term stability is usually not as good as other precision resistors, but its advantage is that the highest accuracy can reach ±0.01%, which is the mainstream technology in high-voltage, high-resistance and high-precision applications. In addition, Thick Sound Group's product strengths include the carbon film series of universal resistors for electronic, commercial and industrial applications.
The parameters of the thick acoustic thick film resistor series mainly include the following aspects:
Specification range: This series of patch resistor specifications range from 0201 to 2512, to meet different size requirements.
Power range: The power range can be from 1/32W to 6W, suitable for different power requirements.
Resistance range: The resistance range can be from 0.01Ω to 100MΩ, covering the needs from ultra-low resistance to high resistance.
Accuracy level: Accuracy level includes 0.5%, 1%, 2%, 5%, 10%, 20% to meet the application scenarios with different accuracy requirements.
Type and installation method: model including 01005/0201/0402/0603/0805/1206/1210/1812/2010/2512, installation method for surface adhesive.
Resistance deviation: There are many options for resistance deviation, such as D=±0.5%; F=±1%; G=±2%; J=±5% to adapt to different accuracy requirements.
Temperature coefficient: Some products have a specific temperature coefficient, such as ±400ppm/ ° C, which is particularly important for applications that require stability over a certain temperature range.
Maximum operating voltage: For network resistance/array exclusion, the maximum operating voltage information is also one of the important parameters.
Special series: There are also special series such as ESD antistatic thick film patch resistor, HV high voltage thick film patch resistor, which are designed for specific application needs.
These parameters demonstrate the variety and flexibility of the thick acoustic thick film resistor family to meet a wide range of needs in the electronics industry.
