What Is a Carbon Film Resistor?

Carbon film resistors are prepared by coating carbon ink, graphite, and fillers with an organic binder as a suspension on an insulating substrate, and polymerizing by heating. It used to be the most used resistor in electronics, electrical appliances and information products, the cheapest price, and high reliability in quality and stability.

Carbon film resistor is a kind of film resistor, it is used

Resistors are an essential and most used component in electronic products. It has many types and shapes, and the classification methods are different. Generally, it can be divided into fixed resistors, variable resistors, and sensitive resistors. In addition, it can be classified by purpose, structure, and lead form.

Fixed resistors can be divided into carbon film resistors, metal film resistors, metal oxide film resistors, metal glass glaze resistors, inorganic solid resistors, organic solid resistors, chemically deposited film resistors, and synthetic carbon film resistors.

Variable resistors can be divided into semi-adjustable resistors and potentiometers.

Sensitive resistors can be divided into thermistors, photoresistors, piezoresistors, magnetoresistive resistors, temperature sensitive resistors, gas sensitive resistors, and force sensitive resistors.

Wire-wound resistors can be divided into precision wire-wound resistors, general-purpose wire-wound resistors, power-type wire-wound resistors, and high-frequency wire-wound resistors.

According to different uses, it can be divided into general-purpose resistors, high-resistance resistors, high-voltage resistors, high-frequency non-inductive resistors, and precision resistors.

According to the structure, it can be divided into cylindrical resistors, tube resistors, disc resistors, chip resistors, and button resistors.

According to the different lead forms, it can be divided into axial lead resistors, co-lead resistors, leadless resistors, and radial lead resistors.

Fusible resistors can be divided into repairable and non-repairable fusible resistors. ^[2]

Good stability, small negative temperature coefficient, good high frequency characteristics,

Widely used in AC, DC circuits of radios, televisions, computers, video recorders and various instruments, such as RT-0.25, RT-0.5, RT-1, RT-2, etc. are popular carbon film resistors, which can be used in radio , Recorders and other less demanding home appliances and various AC and DC circuits. Carbon film resistors such as RT13, RT14, RT15 can be used in circuits such as computers and video recorders due to their high accuracy and small size. ^[2]
