RALEC is a well-known electronic component manufacturer in Taiwan, specializing in the research and production of passive components such as resistors and capacitors. Its thin-film resistor products are known for their high precision, stability, and reliability, and are widely used in precision electronic equipment, industrial control, medical equipment, automotive electronics, and other fields. The following is a detailed introduction to Wangquan thin film resistors:
1、 Characteristics of Thin Film Resistance Technology
Thin film resistors are formed on ceramic substrates (such as alumina) through vacuum deposition technology to form metal thin films (such as nickel chromium alloys), and then the resistance value is precisely controlled through laser resistance adjustment technology. Compared to thick film resistors, thin film resistors have the following advantages:
High precision: The resistance error can be as low as ± 0.1% (such as the 0.1% precision model of 0402 size), suitable for precision circuit design.
Low Temperature Coefficient (TCR): Small temperature drift (usually ≤± 25ppm/℃) ensures higher stability of resistance values during temperature changes.
Low noise: The thin film structure reduces current noise and is suitable for noise sensitive scenarios such as audio and sensors.
Excellent high-frequency characteristics: low parasitic inductance, suitable for high-frequency signal processing (such as RF circuits).
