Fixed resistors are components that are part of an electrical circuit and are used to reduce the flow of electricity. In most cases, they are used to limit current in active components. They always have the same value and their main objective is to oppose the passage of electric current. They are measured in ohms and are usually shown as the number and then the units (for example: 750 ohms).
En Nugar Resistor Technology We are manufacturers of industrial fixed resistors, with exclusive designs designed and designed especially to reduce the flow of electricity silently.
Furthermore, in the manufacturing process we use inorganic materials and rely on technology so that the final result is a resistant, efficient and ecological device.
We want the customer to have a clear idea of our fixed resistors and that is why we provide you with the necessary information so that you do not have doubts when choosing.
When selecting a fixed resistor it is important for the person to consider three key aspects: its value, resistance and nominal power.
As we explained above, the value is measured in ohms. Resistance, on the other hand, indicates the upper and lower limits of actual performance and is measured in positive and negative percentages.
For example, a tolerance of 20% means that the resistor will operate within 20% of the resistance value indicated in the specifications.
The power rating shows the upper limit of power the device can handle and is measured in watts. A general rule to prevent this from happening is to use fixed resistors that have a nominal power twice the actual power needed.
There are two types of fixed resistors: carbon and metal film. The former are designed for general use and are usually quite inexpensive to produce and purchase. These units have a 5% tolerance with power ratings of ⅛ watts, ¼ W and ½ W. The main problem with these devices is that they generate noise.
Fixed metal film resistors are used in contexts where higher tolerance is required. They present a higher level of precision than carbon ones due to the nature of the materials used in their manufacture.
It is really very important to pay attention to the types of devices that exist in order to choose the right one for the circuit in which you want to install it. To go a little deeper into these devices, we are now going to differentiate fixed electrical resistors from coiled ones:
The objective of fixed electrical resistors is to oppose the current in such a way that there is a limitation in the electrical circuit so that the user establishes the amount of current that the circuit will have.
These devices have a defined value that comes from the manufacturer, but when using it, it is necessary to know it so that it is applied correctly.
To do this, it is necessary to calculate the resistance, a process that can be done quickly and easily with the color code.
Fixed wound resistors are those that use a resistor wire wound on air or a dielectric material (it can be ceramic or vitrified).
In any case, this device has great benefits, among which the following stand out:
The quality of the materials we use, added to the good use of the technology we make, have allowed us to create our own manufacturing systems, many of which are exclusive.
That is why, regardless of your needs, rest assured that here you will find the fixed resistors you are looking for. If you have questions about the technical specifications of our products or do not know which one is suitable, you can contact us here.
