Thin film resistor is different from the thick film chip resistor and the latter dominates the market. It is a thin film chip fixed resistor with high accuracy and low temperature coefficient which is made by evaporating a certain resistivity material on the surface of the insulating material. It can be divided into: 1. Carbon film resistors 2. The metal film resistors. 3. Metal oxide film resistors 4. The synthetic film resistors.
Thin film resistor is a kind of high precision resistor. Thin film resistor is different from the thick film chip resistor and the latter dominates the market. It is a thin film chip fixed resistor with high accuracy and low temperature coefficient. Thin film resistor is made by evaporating a resistivity material on the surface of an insulting material, and the insulting material of such resistor is generally ceramic substrate. Thin film resistor is made by evaporating a certain resistivity material on the insulating material, and the major categories are: 1. The carbon film resistor is made by depositing crystallize carbon on a ceramic rod framework. Carbon film resistors have low cost. Stable performance. Wide resistance range. It has low temperature coefficient and voltage coefficient, and is the most widely used resistor at present. 2. The metal film resistors. Coating the alloy material on the surface of the ceramic rods framework by vacuum evaporation . Metal film resistors have higher precision, good stability, and low noise and temperature coefficient than carbon film resistors, thus is widely applied in the instrumentation and communications equipment. 3. Metal oxidation film resistors is made by deposited a metallic oxide layer on the insulating rod. Because it itself is an oxide, it is stable at high temperature and thermal shock resistance with strong load capacity. 4. The synthetic membrane resistor is made by coating the conductive composite suspension liquid on the substrate, therefore, it is also called paint film resistor. Due to its grainy structure of the conductive layer, it produces a lot of noises, and has low precision. It is mainly used in the manufacturing of resistors with high pressure and resistance and small resistors.
