The manufacturing process of carbon film resistors utilizes carbon precipitation on magnetic rods or ceramic tubes,
forming a layer of carbon film crystals on their surface.
By adjusting the thickness of the carbon film and changing the degree of carbon film resistance through grooving,
we obtain the required resistance value and apply epoxy resin on the surface to strengthen the sealing.
The carbon film resistor is made into a color ring resistor series in appearance,
namely the color ring carbon film resistor; The resistance range of this type of color ring resistor is 1Ω~ 10MΩ,
Rated power includes 0.125W, 0.25W, 0.5W, 1W, etc.,
Accuracy range:± 10%,± 5%,± 2%,
this type of carbon film resistor is generally larger in volume and is often used in some inexpensive electronic products,
such as familiar mobile phone chargers, computer power supplies, and other electronic device circuits.

Ceramic insulated power type wire wound resistors are often referred to as cement resistors.
It is widely used in computers, televisions, instruments, instruments, and audio systems.
Cement resistors are wound with resistance wires, generally with high power and larger overall dimensions.
Therefore, it can be easily distinguished from its appearance, power, and model.
In terms of power, it is divided into specifications such as 2W, 3W, 5W, 7W, 8W, 10W, 15W, 30W, 20W, 40W, etc.
The common model is SQP cement resistor, which adopts an industrial high-frequency electronic ceramic shell, with good heat dissipation and excellent insulation performance.
Its insulation resistance can reach 100MR, and it also has excellent flame retardant and explosion-proof properties.
The resistance wire is made of alloy materials such as constantan, manganese copper, nickel chromium, etc., which have good stability and overload capacity.
The resistance wire is crimped with the solder lead wire. In the event of a load short circuit, it can quickly fuse at the crimping point, providing protection for the circuit.
Good heat resistance, low temperature coefficient, and low noise.
High load power, flame retardant.
Operating environment temperature: -55 ℃~+125 ℃

What is The function of the resistor?
The obstruction effect of an object on the passage of current is called resistance, and the components made by utilizing this obstruction effect are called resistors, abbreviated as resistors.
Resistors are the most widely used type of circuit components, accounting for over 30% of the total number of components in electronic devices. Their quality has a great impact on the stability of circuit operation.
In a circuit, the main function of a resistor is to stabilize and regulate the circuit
Current and voltage, which play a role in voltage reduction, voltage sharing, current limiting, shunt, isolation, filtering (in conjunction with capacitors), matching, and signal amplitude regulation.
The symbol of resistors in circuits: Resistors are the most basic and common electronic components in electronic circuits, and resistors are generally represented by written symbols such as "R", "RN", "RF", "FS", etc.

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.
