Physical Characteristics
The main physical characteristic of an aluminum housed resistor is converting electrical energy into heat energy, which can also be said that the aluminum housed resistor is an energy-consuming component, and when current passes through it, it generates internal energy. Resistors are usually used in circuits to divide voltage and current. For signals, both AC and DC signals can pass through resistors.

Application Range
It is suitable for use in power supplies, inverters, servo systems, and in harsh environments with high requirements, with a long service life. The tolerance is 10%, 5%, 3%, 2%, 1%, and 0.5%. It can also be assembled into high-power models according to customer needs. In addition, it can be customized to meet the specific requirements of customers and combined into a high-power or high-power resistor box in series.


Aluminum housed resistor manufacturers square wire wound resistors (wound resistors), commonly known as cement 

electrical groups, use nickel, chromium, and alloy resistance wire made of other high-resistance materials such as iron, 

wrapped around an alkaline heat-resistant ceramic body. The resistance wire is coated with a protective material that is 

resistant to heat, humidity, corrosion, and flames, and then encapsulated in ceramic with a special non-flammable cement 

filler. Their advantages include high resistance accuracy, low noise, good heat dissipation, and high power consumption. 

They are mainly used in the power level part of amplifiers. The disadvantages are that the resistance is not very high, the cost is

high, and they are not suitable for use in high-frequency circuits due to their high inductance.
