50W ceramic resistor 1R/2/3/4/5/6/8/10/12/20/25/100ohm /200 ohm

Product description

Cement resistance is a resistance encapsulated in cement (in fact, it is not cement but a refractory material, commonly known as cement).

Resistors are wound on non-alkaline heat-resistant porcelain, fixed by heat, moisture and protection

Corrosion-resistant material, the wire wound resistor body is packed into a square porcelain box, with special non-combustibility

Heat resistant cement filled seal. Cement resistance is very common

There are two types of cement resistors and cement wirewound resistors. . Cement resistance is a wire wound resistor is a high-power resistor that allows greater current to pass through. it with normal resistance, but can be used in high current situations, such as in series with the motor, to limit motor starting current, the resistance value is generally small. Cement resistors have the characteristics of large size, shock resistance, moisture resistance, etc.

Large resistance, good heat resistance, good heat dissipation, low price,and so on, widely used in power adapters, audio equipment, frequency dividers, instruments, televisions, automobiles and other equipment.
 

Feature

1. Good shock resistance, moisture resistance, heat resistance and heat dissipation;

2. Insulation, printed circuit board;

3. Wind the wire on the porcelain rod and then weld the joint, measure the resistance value, and prolong the service life;

4. The temperature coefficient of resistance is small and changes in a straight line;

5. High resistance adopts metal oxide film body (Mo) instead of winding method;

6. Resist short-time overload, low noise, and the resistance value remains unchanged for many years;

7. Good explosion-proof performance
