Cement Fixed Resistors

Cement Fixed Resistors

Cement fixed resistors are electronic components that are used to limit the flow of electric current in a circuit. They are called "cement" resistors because their construction involves a ceramic core that is coated with a layer of cement or other high-temperature adhesive material. This coating helps to protect the resistor from damage due to heat and vibration.

Cement fixed resistors are known for their high power handling capabilities, which makes them suitable for use in high-current applications. They also have a low noise level and good temperature stability, which makes them ideal for use in precision applications.

Cement fixed resistors are available in a range of values, power ratings, and tolerances to suit different circuit requirements. They are typically color-coded to indicate their resistance value, and they can be easily mounted on a circuit board using solder or other methods.

Specification of Cement Fixed Resistors

Application of Cement Fixed Resistors

Cement fixed resistors are a versatile component that is widely used in electronic circuits for a variety of applications.

• Voltage regulation: Cement fixed resistors are used to regulate voltage in electronic circuits by creating a voltage drop across the resistor. This is often used in power supply circuits.

• Current limiting: Cement fixed resistors can be used to limit the flow of current in an electronic circuit, which helps to protect other components from damage due to excessive current.

• Timing circuits: Cement fixed resistors are used in timing circuits, where they help to set the time constant of the circuit.

• Amplifier circuits: In amplifier circuits, cement fixed resistors are used as feedback resistors to control the gain of the amplifier.

• Sensor circuits: Cement fixed resistors can be used in sensor circuits to measure temperature, light, or other environmental variables.
