What you Need to Know About Custom Resistors

Resistors are an integral part of any electrical or electronic circuit. Resistors do not do much to clearly be identified within the circuit. Resistors as the name suggests resist the flow of current within a circuit. This is referred to as resistance and is gauged using Ohms denoted by the Greek letter omega. A resistor limits the quantity of power that gets to the other components of the system. If for instance there is too much current going to a light bulb it will be damaged. In this sense the resistor protects the other parts of the circuit.

Varying systems require varying levels of resistance. A custom resistor is one made for a particular complex. They are designed for different systems and uses. When picking a resistor for a system one should know how much heat the resistor can endure before it is rendered useless. Resistors become warmer when current passes through them.

A resistor which has higher limit will become warmer than one with lower limit. The substance a resistor is made of may not be able to withstand some levels of heat and will be damaged. A custom resistor should be put together with consideration of heat produced in use.

Tolerance refers to the accuracy of a particular resistor. It is not possible to create a custom resistor that is absolutely correct for a system and the current flowing through it. Tolerance is gauged by plus or minus a certain percentage. For instance, a 5% resistor with a value of 200 ohms has a resistance of between 190 ohms and 210 ohms.

Custom resistors can be made of carbon, ceramics or metal. As shown above resisters heat up as power flows in them. The substance used to make them should endure the high temperature and not combust or melt. Many of the Available resistors in the market are made of carbon and metal.

They come in either surface-mount or through-hole mount termination types. The main material for Through-hole mount are either made of carbon, metal film or very thin metal foil. The former is much cheaper. Surface mount resistors, on the other hand, are normally made from thin or thick metal foil. Normally, resistors that are made from thin foil are cheaper than those made from thick foil. Variable resistors are good option to the static resistors. The resistors can also be regulated to operate within a range of values. These resistors are also known as rheostats and can often be found in components such as volume knobs.
