RX27 10W 20W 5W Cement Resistor 1RJ 2RJ-Diverse Power Levels for Optimal Performance
Cement resistor
Cement resistors are usually used in occasions with high power and current, with 2W, 3W, 5W, 10W or even greater power, such as air conditioners, televisions, and other electrical appliances with power above the 100-watt level, basically cement resistors will be used
Cement resistor, is a cement (in fact, not cement but refractory mud, this is commonly called) potted resistor, that is, the resistance wire wound on non-alkaline heat-resistant porcelain, the outside with heat-resistant, moisture-resistant and corrosion-resistant materials to protect and fix, and the wirewound resistor body into the square porcelain frame, with special non-flammable heat resistance
Sealed with mud filling. There are two types of cement resistors: ordinary cement resistors and cement wirewound resistors. The shape of the cement resistor is shown in the figure. Cement resistors are a type of wirewound resistor, which is a type of resistance with higher power and can allow the passage of larger currents. Its function is the same as that of general resistance, but it can be used in occasions with large currents, such as series connection with the motor, limiting the starting current of the motor, and the resistance value is generally not large. Cement resistors have the characteristics of large dimensions, earthquake resistance, moisture resistance, heat resistance and good heat dissipation, low price, etc., and are widely used in power adapters, audio equipment, audio crossovers, instruments, meters, televisions, automobiles and other equipment.
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
