Cement ceramic resistor is a resistor sealed with refractory mud (commonly known as cement, actually not cement). 

The outer side of the cement resistance is mainly made of ceramic materials (generally divided into high alumina porcelain and feldspar porcelain).

Cement Resistors Characteristic:

1. Shock resistance, moisture resistance, heat resistance, good heat dissipation, low price and other characteristics.

2. Fully insulated, suitable for printed circuit boards.

3. The wire is wound on the porcelain rod and then the joint is welded to make the accurate resistance value and prolong the service life.

4. The high resistance value is made of metal oxide film (MO) instead of winding.

5. Excellent heat resistance, low resistance temperature coefficient, linear change.

6. Resistance to short-time overload, low noise, resistance value has no change over the years.

7. Good explosion-proof performance and protection.
