Types of Resistors

There are many different types of resistors available. Some of the most common are metal and carbon film, carbon composition, and wire-wound resistors.

Carbon Composition Resistors

Carbon composition resistors are made from a mixture of carbon dust or graphene that is combined with a ceramic (clay) binder and fired at high temperature.

The mixture of the electrically conductive carbon/graphene and electrically insulating ceramic allow manufacturers to control the value the resistor.

Wirewound Resistors

The wirewound resistor essentially packages a really long wire into a small package. Made by wrapping wire around an insulating core, wirewound resistors feature parasitic inductance that limits their usage in high frequency applications.

However, more complex winding patterns can be used that reduce or eliminate the inductance of wirewound resistors, allowing them to be used in a wide variety of applications.

Table of Resistor Types, Strengths and Weaknesses

Type of ResistorToleranceStrengthsWeaknesses
Carbon Film Resistor (RT)①The main tolerances are: ± 5%, ± 10%, ± 20%。②Mostly used in less demanding circuit occasions.Low cost of carbon filmPoor stability and large errors
Metal Film Resistor (RJ)①The allowable errors are: ± 0.1%, ± 0.2%, ± 0.5%, ± 1%. ②Mostly used in occasions with high accuracy requirements.Small size, low noise and good stabilityHigh cost
Metal Oxide film resistor (RY)It is suitable for non-combustible, temperature change resistance, humidity resistance and other occasions.Good oxidation resistance and thermal stability
Wire Wound Resistor(RX)Suitable for circuits with low frequency and high accuracy requirements.Precise resistance, stable operation, small temperature coefficient, good heat resistance, and high powerThe resistance value is small, the distributed inductance and distributed capacitance are large, and the manufacturing cost is also high
High power wire wound resistor (RX)Suitable for high power occasions, the rated power is generally more than 1W.Stable work, good heat resistance, small error range
Organic Solid Resistor (RS)Generally used in places where the load cannot be disconnected and the work load is large, such as the circuit where the audio output is connected to the headsetStrong overload capacity, high reliability and low priceLow Precision
Fusing Resistor (RF)It is used in series with high value and circuit components that need to be protected. It is commonly used in power supply and secondary power supply circuits.
Cement Resistor(RX)A Good choice in a circuit where a large amount of current is being passed through a resistor and with it needing to be resistant to high heat and flame.Good explosion-proof performance, complete insulation, shock resistance, humidity resistance, heat resistance and good heat dissipationLarge size, high heat generation during use, easy to radiate
0 ohm Resistor①On the PCB for debugging convenience or compatible design and other reasons②Can be used as a jumper③Wiring
Power Type Wire Wound Non-inductive Resistor (aluminum shell resistor)It is suitable for high-power circuits and harsh magnetic fields, so it is often called a power resistor.
Network Resistor(Wire-wound Resistor)Generally used in digital circuits, instrument circuits and computer circuits, such as attenuators in instrument circuits.Easy assembly and high installation density
