Through Hole Resistors

Through hole resistors are a type of resistor where the body is designed to be mounted in a hole drilled in a board so that the component is passed through the board. This type of resistor is commonly used in the manufacture of circuit boards, as it allows the boards to be made smaller and more efficient. The RLR20C1503GPBSL through-hole resistor is one of the most used through-hole resistors in the industry, and its application field and working principle is discussed in this article.

Application field of RLR20C1503GPBSL

RLR20C1503GPBSL resistors are widely used in different applications, from the computer industry to consumer electronics. Typically, they are used in power circuits and in DC-to-DC converters. The resistor consists of a body composed of epoxy resin and a metallic layer, usually casted with copper, that provides an electrical conduction path. The resistor surface is covered with a soldermask that adds a layer of protection against short-circuit. The resistors are also resistant to heat and shock, allowing them to be used in harsh environment.

The RLR20C1503GPBSL through-hole resistor is also used as a filter or a noise filter because of its high resistance to noise and EMI. It is also used to dissipate power in circuits and to control the current flow in high power applications. The resistor is also used to reduce temperature during soldering or welding, as well as to provide resistance against temperature changes.

Working Principle of RLR20C1503GPBSL

The RLR20C1503GPBSL resistor functions by creating an electrical resistance between two points. This process is based on the Ohm’s Law which states that the current passing through the resistor is proportional to the voltage applied across it. The voltage applied across the resistor creates an electrical field around the resistor, and the current flowing through it is proportional to this field.

The RLR20C1503GPBSL through-hole resistor is composed of two contacts that make an electrical connection when joined by soldering. If a voltage is applied across these two points, electrons will start flowing between them and create an electrical current. The current will then flow through the resistor and will be proportional to the voltage applied, thus creating the electrical resistance.

The resistor has a tolerance value that defines the accuracy of the resistance. This value is represented with a certain letter (for instance K for 10%) which indicate the maximum tolerance of the resistance. The tolerance level is important to consider when choosing a resistor, since it will allow to achieve the desired current through the resistor.

Conclusion

The RLR20C1503GPBSL is one of the most used through-hole resistors in the industry. Its application fields include the computer industry, consumer electronics, power circuits and DC-to-DC converters. It is also used in noise filtering and temperature control. The resistor functions based on the Ohm’s Law, and its resistance is determined by the voltage applied across two points. The tolerance of the resistance is also an important parameter to consider when selecting this type of resistor.
