Thin film resistor

By evaporating a certain resistivity material onto the surface of the insulating material, it is made. The main contents are as follows:
1 Carbon film resistor
Depositing crystalline carbon onto a ceramic rod skeleton. Carbon film resistors are currently the most widely used resistors due to their low cost, stable performance, wide resistance range, low temperature and voltage coefficients.
2 metal film resistors.
The alloy material is evaporated onto the surface of the ceramic rod skeleton using vacuum evaporation method. Metal film resistors have higher accuracy, better stability, lower noise, and temperature coefficient than carbon film resistors. It is widely used in instruments and communication equipment.
3 Metal oxide film resistor
Deposit a layer of metal oxide on the insulating rod. Due to its inherent oxide nature, it is stable at high temperatures, resistant to thermal shock, and has strong load capacity
4 Synthetic film resistor
Coating a conductive composite suspension on a substrate is also known as a paint film resistor. Due to the granular structure of its conductive layer, it has high noise and low accuracy. It is mainly used to manufacture high-voltage, high resistance, and small resistors.
