Resistors

  • What is resistance,Electrical Resistor?


    Resistor is generally directly called resistance in daily life. It is a current limiting element. After the resistor is connected in the circuit, the resistance value of the resistor is fixed, generally two pins, which can limit the current through the branch connected to it. A resistor whose resistance cannot be changed is called a fixed resistor. Those with variable resistance are called potentiometers or variable resistors. The ideal resistor is linear, that is, the instantaneous current through the resistor is directly proportional to the applied instantaneous voltage. Variable resistor for voltage division. One or two movable metal contacts are tightly pressed on the exposed resistor. The contact position determines the resistance between either end of the resistor and the contact.Wirewound Resistors。

    The terminal voltage has a definite functional relationship with the current, which reflects the ability of converting electric energy into other forms. It is represented by the letter R, and the unit is Ohm Ω. Actual devices such as bulbs, heating wires, resistors, etc. can be expressed as resistor elements.

    The resistance value of the resistance element is generally related to the temperature, material, length and cross-sectional area. The physical quantity measuring the resistance affected by the temperature is the temperature coefficient, which is defined as the percentage of the resistance value when the temperature increases by 1 ℃. The main physical feature of resistance is to change electric energy into heat energy. It can also be said that it is an energy consuming element, and the current passes through it to produce internal energy. Resistance usually plays the role of voltage division and shunt in a circuit. For signals, both AC and DC signals can pass through resistors.Carbon & Metal Film Resistors。


    What is the resistance classification?


    Classification by volt ampere characteristics

    For most conductors, the resistance remains almost constant at a certain temperature. This kind of resistance is called linear resistance. The resistance of some materials obviously changes with the current (or voltage), and its V-A characteristic is a curve. This kind of resistance is called nonlinear resistance. Under the action of a given voltage (or current), the ratio of voltage to current is the static resistance at the working point, and the slope on the V-A characteristic curve is the dynamic resistance. The expression of nonlinear resistance characteristics is complex, but these nonlinear relations have been widely used in electronic circuits.


    Classification by material

    a. The wire wound resistor is formed by winding the resistance wire. The resistor is made of high resistance alloy wire wound on the insulation skeleton, and the outside is coated with heat-resistant glaze insulation layer or insulating paint. Winding resistance has low temperature coefficient, high resistance accuracy, good stability, heat resistance and corrosion resistance. It is mainly used as precision high-power resistance. Its disadvantages are poor high-frequency performance and large time constant.

    b. Carbon synthetic resistor is made of carbon and synthetic plastic.

    c. The carbon film resistor is made by plating a layer of carbon on the ceramic tube and depositing the crystalline carbon on the ceramic rod skeleton. Carbon film resistor is the most widely used resistor at present because of its low cost, stable performance, wide resistance range and low temperature coefficient and voltage coefficient.

    d. The metal film resistor is formed by plating a layer of metal on the ceramic tube, and the alloy material is evaporated on the surface of the ceramic rod skeleton by vacuum evaporation.

    Compared with carbon film resistance, metal film resistance has the advantages of high precision, good stability, low noise and low temperature coefficient. It is widely used in instruments and communication equipment.

    e. The metal oxide film resistor is formed by plating a layer of tin oxide on the porcelain tube and depositing a layer of metal oxide on the insulating rod. Because it is an oxide itself, it is stable at high temperature, resistant to heat shock and strong load capacity. According to its purpose, it has general purpose, precision, high frequency, high voltage, high resistance, high power and resistance network.


    special resistor

    1. Fuse resistor: also known as fuse resistor, it plays the dual role of resistance and fuse under normal conditions. When the power of the circuit exceeds the rated power due to fault, it will fuse like a fuse to disconnect the connecting circuit. The fuse resistance is generally small (0.33 Ω ~ 10K Ω) and the power is also small. Common models of fuse resistors include: rf10 type, rf111-5 symbol type of fuse resistor, rrd0910 type, rrd0911 type, etc.

    2. Sensitive resistor: it means that its resistance value is sensitive to certain physical quantities (such as temperature, humidity, light, voltage, mechanical force, gas concentration, etc.). When these physical quantities change, the resistance value of the sensitive resistor will change with the change of physical quantities, showing different resistance values. According to the sensitivity to different physical quantities, sensitive resistors can be divided into thermal sensitive, humidity sensitive, photosensitive, pressure sensitive, force sensitive, magnetic sensitive, gas sensitive and other types of sensitive resistors. Almost all the materials used in sensitive resistors are semiconductor materials, which are also called semiconductor resistors.

    The resistance value of thermistor changes with temperature, and the temperature rise resistance is a negative temperature coefficient (NTC) thermistor. Negative temperature coefficient thermistors are widely used, which can be divided into ordinary negative temperature coefficient thermistors; Voltage stabilizing negative temperature coefficient thermistor; Temperature measurement type negative temperature coefficient thermistor, etc. Photosensitive resistance is that the resistance value of the resistance changes with the intensity of the incident light

    When the incident light is enhanced, the photoresist decreases, and when the incident light is weakened, the resistance increases.metal oxide resistors,Fixed Resistors,Carbon Film Resistor,thin film chip resistors
