RLR20C27R4FRB14

Through Hole Resistors are an important type of resistors used in electronic circuits, mainly for controlling the flow of current in circuits. The RLR20C27R4FRB14 is a Through Hole Resistor, featuring a threaded base type that is designed to be screwed into pre-drilled mounting holes, and a radial lead type that is used for through-hole mounted resistors. This type of resistor is used for applications where it\'s necessary to protect the nodes in an electrical circuit from dangerous spikes or other forms of electrical damage, such as causing excessive current. It is also used in applications where it is necessary to control the current in a circuit to maintain a desired level. This resistor can be used in a variety of applications, including energy meters, power supplies, motor controllers, and even in lighting applications.

This resistor is made up of five main components: an inner shell, a copper wire, a dielectric, a contact collar, and an outer shell. The inner shell consists of a ceramic core with highly conductive metal or layers of metal, such as silver or gold, that are used to dissipate heat generated from current. The copper wire is used to connect between the inner shell and the dielectric. The dielectric, typically a high quality ceramic material, helps insulate and protect the copper wire. The contact collar is put in place to make the contact between the copper wire and the dielectric. Lastly, the outer shell is designed to encase the entire assembly and help form an effective barrier against dust, dirt, and moisture.

The RLR20C27R4FRB14 features a resistance value of 27 ohms, and it has a power rating of 4 watts. It comes with a tolerance of 5%, which means that the stated resistance value can vary by up to 5% at normal operating temperatures. It also has a temperature coefficient of 100ppm/°C, which means that the resistance will change by up to 100ppm/°C when the operating temperature changes. Finally, it comes with a maximum operating temperature of 155°C. This is important because it means that the resistor can be used in high temperature environments and not suffer any damage.

The working principle of the RLR20C27R4FRB14 is relatively simple. When a voltage is applied across the contacts, a current flows through the resistor. As the current passes through the resistor, it is reduced due to the resistor\'s resistance, or impedance, preventing the voltage from increasing excessively. In this way, the voltage is regulated and the current is limited. The resistor can also act as a filter, blocking certain frequencies of current while allowing others to pass.

The RLR20C27R4FRB14 Through Hole Resistor can be used in applications such as switching power supplies, cell phone chargers, LED lighting, and automotive electronics. It can also be used to protect sensitive electronic components from excessive current flow by limiting the current that passes through them. In addition, the resistor can be used to control the speed of a motor, as well as the temperature in an electronic device. All of these are just a few of the countless potential uses for this resistor.

Overall, the RLR20C27R4FRB14 Through Hole Resistor is an essential component in any electronic circuit. It is designed to limit current flow and protect sensitive components from damage, while also acting as a filter in some circuits. In addition, the resistor can be used in a variety of applications to control the speed and temperature of various electronics. With its high power rating and excellent tolerance, the RLR20C27R4FRB14 is one of the most reliable resistors on the market today.
