WEET Suggestion for using resistors:

It is recommended to leave a power margin of 1.5 times when using resistors in the circuit. For example, if the voltage in the circuit is 100V, the current is 0.01A, and the calculated power is P=100 * 0.01=1W, then the resistor cannot be used as 1W. If there is no 1.5W resistor, a 2W resistor needs to be used.

Advantages of cement resistance:

1. Features such as shock resistance, moisture resistance, heat resistance, good heat dissipation, and low price.

2. Fully insulated, suitable for printed circuit boards.

3. Wire winding on the porcelain rod and then welding the joints to produce accurate resistance values and extend service life.

4. High resistance values are made using metal oxide film (MO) instead of wire winding.

5. Excellent heat resistance, low resistance temperature coefficient, and linear variation.

6. Short term overload resistance, low noise, resistance value unchanged over the years.

7. Good explosion-proof performance, providing protection.

What are the differences between carbon film resistance and metal film resistance

1. The carbon film resistance has a negative temperature coefficient, while the metal film resistance has a small positive temperature coefficient;

2. Carbon film resistance is an ordinary resistance, and its accuracy is generally not very high, while metal film resistance has higher accuracy than carbon film resistance. However, due to the improvement of current technology, this method is sometimes not very desirable;

3. The appearance of carbon film resistors is mostly khaki or pink, while the appearance of metal film resistors is mostly blue;

4. By looking at the color of the protective paint, the black protective film is carbon film resistance, while the bright white protective film is metal film resistance.

What are the characteristics of carbon film resistance and metal film resistance

1、 Carbon film resistance

For the carbon film resistance, it uses carbon to precipitate on the magnetic rod or porcelain tube, and at the same time forms a layer of crystalline carbon film on its surface. By changing the thickness of the carbon film and changing the degree of the carbon film resistance by grooving, the required resistance value is finally obtained. Finally, the surface is coated with epoxy resin to strengthen the sealing. The appearance color is basically earthy yellow, but there are also other colors, such as pink.

The color ring is composed of four rings. The resistance range is 1 Ω~10M Ω. The rated power is 0.125W, 0.25W, 0.5W, 1W, etc. The accuracy range is ± 10%, ± 5%, ± 2%. This resistance is generally large and is often used in low-cost products, such as power supply products and chargers. This type of resistance is not recommended for starting resistance, because the impact resistance is relatively defective.

2、 Metal film resistance

As for the metal film resistor, it is formed by vacuum evaporation or infiltration on the ceramic pipe rack to form a layer of metal film, which is attached to the surface of white ceramics. It is cut to adjust the resistance value to obtain a more precise resistor. This resistor has high precision, small volume, good stability and high cost. It is usually used in wireless electronic equipment, especially in occasions with higher precision requirements. Its appearance color is mostly blue.

Featuring consistency and stably-controlled, these carbon film resistors with reasonable prices are widely and largely be used in the electronic, electrical and information industries.
This resistor is a ceramic bar tightly coated with a carbon film which is composed of carbon separately from organic compound through the treatment of high temperature vacuum.
After the carbon coated bar is connected with proper joint and engraved with grooves, its surface is finished with epoxy resin so that the bar is enclosed with a protective film.

Application: all kinds of customer devices.
