RWR81S49R9FRB12

The RWR81S49R9FRB12 resistor is a type of through-hole resistor designed for a variety of commercial, industrial and consumer applications. It is engineered to be highly reliable, accurate, and easy-to- use. Through hole resistors are those components that are inserted into a circuit board or breadboard with a hole or pads for the contact pins, as opposed to surface mount resistors. In terms of applications, the RWR81S49R9FRB12 resistor is typically found in analog circuits, digital circuits, high input impedance circuits, audio circuits, automotive circuits, and various others.

The working principle of this type of resistor is relatively simple. Its main function is to create a resistive pathway that limits the current and voltage within a circuit. The resistance value of the resistor is configured by the choice of its materials and design, and can range from a few ohms to a few mega ohms. This is why through hole resistors come in a huge variety of shapes, sizes and classes. The resistor’s various parameters, such as resistance value, power rating, and dielectric strength, are often printed or stamped onto the body of the resistor.

Apart from providing resistance, through-hole resistors are also used to perform other functions, such as noise suppression, voltage division, and voltage regulation. In general, there are three main categories of through-hole resistors, namely, fixed resistors, variable resistors, and precision resistors. Each have their own distinct characteristic, advantages and disadvantages. The RWR81S49R9FRB12 resistor is a type of fixed resistor. Fixed resistors can be further divided into types, such as carbon composition resistors, wire-wound resistors, metal-film resistors, metal-oxide film resistors, thick-film resistors, and others. The characteristics of each type of resistor vary, but all provide a consistent and reliable resistance to electric current.

The main benefit of fixed resistors compared to the other two categories (variable and precision resistors) is that they are very consistent in providing the same resistance over time and have excellent temperature stability. This makes them suitable for a wide range of applications, such as LED lighting, audio amplifier circuits, power supply circuits, and many others. The RWR81S49R9FRB12 resistor also provides excellent tolerance, which is the maximum acceptable deviation of a resistor’s resistance from its nominal value. This tolerance is typically between 1% and 10%.

The RWR81S49R9FRB12 resistor is a versatile and reliable component that is suitable for a variety of applications. Its resistance and tolerance are configured depending on the specific needs of the circuit. As always, proper attention must be given to selection and installation of any component to ensure its longevity and reliability.
