Why You Should Use a Precision Resistor
A precision resistor is a small, linear electrical component that has an extremely high degree of stability. They are used in a wide range of applications and are highly accurate. These precision resistors are also used in commercial aviation, where onboard instruments must be very accurate and handle the critical conditions of an airplane. They are also used in audio devices. They are ideal for a wide variety of high-speed electronic equipment. Here are some reasons why you may want to use a precision RC resistor in your next project.
A precision resistor's tolerance value plays a major role in a circuit's accuracy. The tolerance value is the difference between the nominal and actual resistor values. There are many types of resistors available, including wire wound, metal film, foil, bare metal, and thin film. All of them offer different levels of resistance and temperature coefficients. A ppm/degC tolerance value means that every 1M Ohm of resistance increases by 110 Ohms for each degree of temperature. Therefore, a ppm/degC tolerance value of 1.1 ohms for a 100k-ohm resistor is acceptable.
In addition to the tolerance value, the resistance value is an important consideration in measuring the precision of a circuit. The nominal value is the range between two ranges. The tolerance value plays a significant role in the accuracy of the circuit. There are several types of power resistors technology. The most common are thin film, wirewound, and metal film. Each type of technology has different characteristics and can produce the same or different results. In addition, the temperature coefficient is an important measurement metric. For instance, 110 ppm/degC represents 110 Ohms per 1M Ohm increase. This would mean 11 ohms for a one-million-ohm resistor.
The tolerance value of a precision resistor is an important consideration for any design. As a result of their high price, a precision resistor must meet stringent quality standards. Resistance with a tolerance value of more than 0.1 ppm is incompatible with certain circuits. It will not work in these circuits, as they are not intended for use in temperature-sensitive environments. It is crucial to ensure the accuracy of a circuit.
The tolerance value of a precision resistor is an important parameter for accurate design and performance. It relates to the resistance's ability to withstand temperature changes. If the TCR is too high, the device cannot function. Instead, it can cause damage to the circuit and destroy electrical components. As a result, the tolerance value should be lower than the nominal value. This is important because a higher temperature coefficient means lower resistance.
Generally, the accuracy of a precision resistor is ±/0.01% when it leaves the factory. But the value can fluctuate up to 300ppm after it is soldered onto a PCB. It can be affected by humidity, static electricity, and even temperature differences. For these reasons, a precise resistance resistor should be the primary consideration when designing a circuit. So, the voltage coefficient of a precision resistor is important.
