China factory Resistor 1W 2W 3W 5W 11W 15W 17W 20W 25W ceramic Cement Resistor Cement Resistors

product name:

Cement resistor 5W 10W 0.25R 0.5R 3R 27R 12R 100R 5% ceramic resistor

product description:

Cement 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, and placing the wire wound resistor body into a square porcelain frame, sealed with special non combustible heat-resistant cement. Cement resistor is a type of wire wound 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, and the resistance value is generally not large. Cement resistors have characteristics such as large overall size, shock resistance, moisture and heat resistance, and good heat dissipation at a low price.

Product Features:

Advantages of Cement Resistors
Shock resistance, moisture resistance, heat resistance, and good heat dissipation;
Insulation, suitable for printed circuit boards;
Winding wires on the porcelain rod and then welding the joints to produce accurate resistance values and extend service life;
High resistance value is made by using metal oxide film instead of wire winding method;
Good heat resistance, low resistance temperature coefficient, and linear variation;
Short term overload resistance and low noise;
Good explosion-proof performance and protective effect;

Good explosion-proof performance, good heat resistance, low resistance temperature coefficient, good explosion-proof performance, and long service life for protection,Strong load capacity, cement resistance has good durability, shock resistance, moisture resistance, heat resistance, and good heat dissipation, dust prevention, and corrosion prevention
