How to Select SMD Resistors



How to Select SMD Resistors

Surface-mounted resistors are resistors that contain numerical figures in codes similar to the ones used on axial lead-type resistors.
These resistors use SMT technology to decrease the proportions of the materials used. In the process, the time spent to produce a circuit gets reduced as well. While they are clearly advanced and useful, you should know a few things before using them.
Right up ahead, we discuss the things to consider while selecting SMD resistors. So without further ado, let’s get into it!

How to Select the Right SMD Resistor

These are the factors you should consider while choosing an SMD resistor.

Type

Depending on their sizes and designs, SMD resistors are classified into many types. Before selecting a resistor, you must determine its type according to your purpose. For example, general-purpose resistors are for standard use. Again, if you want more eco-friendly resistors, you can get one with those particular specifications.

Power

If your chip resistor can deliver high intensity of power, it means that it is more durable. To make sure they can supply better power dispersion, exclusive components and designs are used by these resistors. For larger machines and high current operations, powerful resistors are more suitable.

Resistance

Certain devices also require resistors rich in resistance. For example, while using a circuit to measure temperature, you'll need such a resistor. Besides, they're also used with similar circuits containing high resistance. These resistors usually have denser films and have more stressed tolerance.

Accuracy

Chip resistors that showcase greater accuracy don’t let resistance fluctuate under the influence of temperature fluctuations. They are available in both thin and dense film designs. If you need to have more stable resistor figures with temperature shifts, you will need resistors with high accuracy.

Sensors

In many cases, you will require resistors that can identify current and transform it into voltage. Here, the amount of voltage needs to correspond with the amount of current passing through the system. While doing so, you will need current sensor resistors. These resistors function by causing voltage drops.

Final Words

Other than these key factors, there are a few other factors behind the selection of SMD resistors. You must also consider the frequency and chemical stability of the resistors. But if you keep the discussed factor in mind, you’ll easily be able to meet all selection criteria.
