In general the Cement / Ceramic Resistor is a robust electronic component designed for applications requiring a low resistance value and the ability to dissipate higher power.
Features:
- Cement / Ceramic resistor is a resistor sealed with fire-resistant clay, which involves winding the resistance wire onto a non alkaline heat-resistant porcelain piece, wrapping it with heat-resistant, moisture-resistant, and corrosion-resistant materials.
- Cement / Ceramic resistor is a type of Through hole resistor that belongs to the category of high-power resistors and can allow large currents to pass through. Its function is the same as general resistors, but it can be used in high current situations, such as connecting in series with an electric motor to limit the starting current of the motor.
- Placing the Through hole resistor body into a square porcelain frame, sealed with special non combustible heat-resistant cement.
- The resistance value is generally not large.
- Advantages of Cement / Ceramic Resistors:
- Have characteristics such as large overall size shock resistance, moisture resistance, Heat resistance, and good heat dissipation at a low price, Insulation, suitable for printed circuit boards.
- Through hole on the porcelain rod and then welding the joints to produce accurate resistance values and extend service life.
- Good heat resistance, low resistance temperature coefficient, and linear variation.
- Short term overload resistance and low noise.
- Typically tolerance, ensuring accuracy in resistance value.
- Good explosion-proof performance and protective effect.
