1、 Cement Ceramic Resistor Product Introduction

Cement resistors are the earliest resistors used and widely used in various products. 

They are the most basic electronic components in electronics, appliances, equipment, and information products. 

It has characteristics such as small size, shock resistance, moisture resistance, heat resistance, good heat dissipation, and low price. 

Cement resistance is fully insulated and suitable for printed circuit boards.

Cement resistance has excellent heat resistance, low resistance temperature coefficient, and a linear variation; 

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

2、 Cement Ceramic Resistor Structure

A. Cement resistance is formed by winding resistance wire on a ceramic rod with good heat resistance or 

a glass fiber substrate with insulation and heat dissipation, forming a wire wound resistance core. 

After passing all tests, the wire wound resistance core is placed inside a ceramic shell of different sizes and shapes, 

sealed with a special non combustible heat-resistant cement electronic filling material, 

naturally dried in the shade and baked at high temperature.

B. High resistance specifications are made using metal oxide film resistor cores instead of wire wound resistor cores.

3、 Cement Ceramic Resistor Applicable scope

Widely used in AC and DC circuits such as electronics, appliances, power supplies, sound systems, and home appliances,

 it is one of the most common ideal electronic components in electronic circuits

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.
