Product description
A cement resistor is a type of wirewound resistor that is a relatively high-power resistor that allows a large current to pass.Its function is the same as the general resistance, but it can be used in the case of large current, such as series connection with the motor, limiting the starting current of the motor, and the resistance is generally small.Cement resistors are usually used for high power and high current.There are 2W, 3W, 5W, 10W or even more power.For example, air conditioners, TV sets, etc.which use power above 100W, basically use cement resistance.

Character:
1.Shock resistance, moisture resistance, heat resistance and 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 welded to the joint to produce accurate resistance value and prolong life.
4. The high resistance value is made by using a metal oxide film body (MO) instead of a winding method.
5. Excellent heat resistance, small temperature coefficient of resistance, a linear change.
6. Short-time overload, low noise, resistance has not changed over the years.
7. The explosion-proof performance is good, play a protective role.
