Thick Film Chip Resistors

Thick Film Chip Resistors

Thick film chip resistors are an essential electronic component used in various electronic devices such as computers, smartphones, and TVs. These resistors are designed to control the flow of electricity in a circuit by detecting the electrical signals and regulating the power to the components in the circuit. Thick film chip resistors are widely used due to their high level of accuracy, cost-effectiveness, and reliability.

The resistors are made up of a resistive layer on a ceramic substrate and coated with conductive terminals at each end. The resistive layer can be made of various materials such as ruthenium oxide, nickel-chromium, or copper oxide. The substrate is usually made of aluminum oxide or silicon dioxide, which provides the base for the resistor. The surface of the resistor is then covered with a protective layer such as epoxy that separates it from the environment.

Rating of Thick Film Chip Resistors

Thick film chip resistors are known for their high level of accuracy and stability. The level of accuracy is determined by the thickness of the resistive layer, which is designed to resist changes in temperature and humidity. These resistors have a wider operating temperature range, making them ideal for use in extreme environments. Additionally, the thick film resistors' stability is enhanced by their high resistance to thermal shock. This means that they can withstand sudden changes in temperature without affecting their accuracy and stability.

The power rating of these resistors ranges from 1/32W to 1W. This allows these resistors to be used in various applications where power dissipation is required. The power rating is determined by the thickness and the surface area of the resistive layer. A larger surface area and a higher thickness provide higher power dissipation.
