Through Hole Resistors

Through Hole Resistors are a common component in printed circuit boards. They are available in a wide range of values, from a few ohms up to several million ohms. Their purpose is to act as a current limiting devices, preventing too much current from flowing through a particular circuit. There are different types of Through Hole Resistors available, including: carbon composition, metal oxide film, and wirewound.

The RWM04103R30JR15E1 is a through hole resistor, used for providing a fixed resistance in a circuit. This particular resistor has a resistance value of 10K ohms, a maximum power rating of 1/4 watt (25 mW), and a tolerance of +/- 15%. It is designed to handle currents up to 20 mA and operate within a temperature range of -40°C to +85°C.

Working Principle

The working principle of through hole resistors is relatively simple. When the resistor is connected to a circuit, it creates a voltage drop across itself, making the current flow through itself. The current will then be limited by the resistance value, preventing too much current from flowing through the circuit.

As the current runs through the resistor, it will dissipate some of the energy as heat, due to the voltage drop across the resistor. Therefore, the power rating of a resistor is an important factor to consider, as it indicates the maximum amount of current that can be handled before the resistor overheats.

Application Field

Through hole resistors can be used in a variety of electronic and electrical circuits. Some common applications for these resistors include signal conditioning, power supply regulation, decoupling, timing circuits, and voltage divider circuits. Additionally, they can make great current-limiting devices.

The RWM04103R30JR15E1 is a great choice for use as a current-limiting device, since its resistance value of 10K ohms is not too high and not too low, so it can handle decent current without overheating, yet still not let too much current pass through it.

This type of resistor is also ideal for use in timer circuits, voltage dividers, and other circuits in which an exact resistance value must be maintained. Its maximum power rating of 0.25 watts ensures that it can handle the current without overheating, and its 15% tolerance allows a degree of error in getting the exact resistance value.
