Through Hole Resistors

Through Hole Resistors are a type of resistor designed to be mounted and connected on a printed circuit board (PCB). These resistors have a hole or through hole in their body which allows them to be mounted directly to the PCB without the need for additional components such as soldering. A wide variety of resistor types are available including carbon, metal oxide, thick film, and wire wound resistors. The type of resistor selected will depend on the design requirements and electrical characteristics required by the circuit.

RLR07C1003FRRE6

RLR07C1003FRRE6 is a through hole resistor created and developed by KOA Speer. It has a power rating of 0.125 W and is a 0805 surface mount package. The tolerance is 5% and it has a temperature coefficient of ±200 ppm/°C. This resistor is available in both 4-terminal and 4-pin configurations. The resistor can handle a temperature range of -55°C to +125°C, but its power rating may decrease at high temperatures.

Application Field

RLR07C1003FRRE6 is an important and widely used component in the electronics industry. It is designed primarily for use in electric circuit boards and devices. It is especially useful for controlling power supply voltages, providing feedback to circuits through voltage and current modulation, and providing electronic noise protection. This resistor is often used in communication systems, computers, digital and analog circuit systems, medical electronics, aerospace, automotive, audio, and video applications.

Working Principle

A through hole resistor works by reducing electric currents to an acceptable level. This is done by dissipating a portion of the energy in the form of heat, hence why it is important to keep the resistor within its operating temperature range. When electrical current is passed through the resistor, it dissipates some of the energy as heat in proportion to the amount of current and resistance within the resistor. The resistor also affects the way voltage is distributed within the circuit, allowing for the circuit to be adjusted according to the requirements.

The resistor is not only designed to reduce electric current, but it also serves as a failsafe in electrical circuits. If the current overloads an electrical component, the resistor will limit the amount of current that can be conducted, thus protecting the device from damage.
