Carbon Film vs Metal Film Resistor

You can choose between carbon film or metal film resistors if you're looking for a resistor. The two have their own unique advantages and disadvantages, so it can be difficult to choose one over the other. By comparing and contrasting these two resistor types: Carbon Film vs Metal Film Resistor, we will be able to help you choose which is right for you.

What are Metal Film Resistors?

Metal Film Resistor

MFRs (metal film resistors) are made by vacuum evaporation or infiltrating metal films onto ceramic pipe frames. Cut the film to obtain a more precise resistance. The film is attached to the white ceramic surface. Metal film resistors are compact, have good stability, are accurate, and are cost-effective. In wireless electronic equipment, metal film resistance is usually used. The high precision features also make them military-grade resistors.

What are Carbon Film Resistors?

Carbon Film Resistors

An insulating substrate is coated with a thin layer of carbon film to form a resistor. Resistors are then protected against moisture and dust by a protective coating. High accuracy ratings, low noise levels, and good temperature stability are all features of these resistors. Low-power applications often use them because they are inexpensive and low-power.

Carbon Film Vs Metal Film Resistor

Compared with carbon film resistors, we'll look at metal oxide film resistors. Both types have strengths and weaknesses, so knowing both will help you choose between them. In addition to private projects, resistors are also suitable for assignments. Carbon film resistors are often regarded as less reliable than metal oxide resistors. Here are a few reasons why:

Price

Low-power applications with no need for precision typically use carbon film resistors because they cost less. Compared to carbon film resistors, which are cheaper and less durable, metal film resistors are more durable and accurate.

Accuracy of Resistance

Different manufacturing processes result in different accuracy levels for resistors. The accuracy of carbon film resistors is generally not very high, and they are very ordinary resistors. The resistance accuracy of metal film resistors is much higher than that of carbon film resistors due to their relatively high production requirements.

Voltage and Temperature Coefficient

Resistance coefficients of Metal Oxide film resistors are better than those of carbon film resistors at high voltages and temperatures. Resistance changes with voltage when the voltage changes. A resistance change is equal to a voltage change, given a change in resistance. In contrast to metal oxide film resistors, carbon film resistors cannot tolerate higher temperatures.

Noise Design

Another reason for comparing Carbon Film vs Metal Film Resistor is Noise Design. There is typically less noise in a metal film resistor than in a carbon film resistor. Heat is dissipated more efficiently and electrical noise is reduced with metal films. Resistors vary from their set values depending on their tolerance. Because metal film resistors have more consistent and uniform layers, they have a higher tolerance.

Faqs

Question 1: How much are metal film resistors compared to carbon film resistors?

Answer: Resistors made of metal film typically cost more than those made of carbon film. They are more accurate and durable than carbon film resistors because of their higher accuracy.

Question 2: Are metal film resistors better?

Answer: According to the application. Despite being more accurate and durable, metal film resistors are generally more expensive and harder to locate. Carbon film resistors are available in many types, but they have lower accuracy and durability than metal film resistors.

Question 3: Which is better: metal film or carbon film resistors?

Answer: It can handle higher temperatures than resistors made of carbon film and operates in a wide range of resistances. As compared to carbon film resistors, metal oxide film resistors produce less noise. The current is kept to a minimum. As a result, less noise is generated.

Question 4: Are metal film resistors better than carbon?

Answer: There are many sizes and types of carbon film resistors available, and they are cheaper. It is also more expensive and more difficult to locate metal film resistors, even though they are more accurate and durable. Your needs should dictate whether you choose metal film or carbon film resistors.

Final Verdict

Now that we have explained the differences between both types of resistors, you can pick whichever you prefer. In circuits with metal film or carbon film resistors, current flow is limited. Unlike carbon film resistors, which use carbon as a conductor, metal film resistors use metal to reduce current flow.
