Through Hole Resistors

A through hole resistor is an electronic component that is used to control the current flow in a circuit. It is also known as a discrete resistor, since it is not physically connected to other active components*. The size, power rating and resistance value determine its application, including the RN50C42R2FBSL.

RN50C42R2FBSL Application Field

RN50C42R2FBSL is a metal resistor. It is a through hole resistor that has a power rating of 0.25W and a resistance of 42 ohms. This resistor is designed to provide current limiting protection on electrical and electronic equipment. It is often used in communication equipment, LED products, power base transceiver stations, lasers and modems.

RN50C42R2FBSL Working Principle

A through hole resistor works on the principle of resistance. As current passes through the resistor, a proportional voltage drop appears across it, depending on its resistivevalue. This voltage drop is proportional to the magnitude of the current and can be calculated using Ohm’s law. The RN50C42R2FBSL has a specific resistance of 42 ohms and is used to control the amount of current in the circuit.

When the resistor is connected to a voltage source and a load resistance, it results in voltage division. The amount of current flowing through the resistor depends on its resistance relative to the load resistance. If the load resistance is higher than the resistor’s, most of the current will flow through the resistor. On the other hand, if the load resistance is lower, then the majority of the current will flow through the load.

Advantages

Through hole resistors have several advantages over other types of resistors. One advantage is that they are easier to inspect than surface mount resistors. The resistor can be easily removed and inspected using magnifying glasses or microscopes. This makes it easier to find the source of problems in a circuit. Furthermore, through hole resistors are less susceptible to damage due to vibration and are less affected by moisture. Lastly, through hole resistors can handle more power than surface mount resistors, allowing them to be used in high power applications.

Disadvantages

The main disadvantage of through hole resistors is that they take up more space in a circuit board. This makes them unsuitable for use in high density applications. Another disadvantage is that they are more expensive than surface mount resistors. Lastly, through hole resistors are less precise than surface mount resistors, which can lead to inaccurate readings in some installations.

Conclusion

Through hole resistors are widely used in many electronics applications due to their durability, reliability and ease of inspection. The RN50C42R2FBSL is a common through hole resistor with a power rating of 0.25W and a resistance of 42 ohms. It is used to control the amount of current in a circuit and is suitable for communication equipment, LED products and other applications. Despite its advantages, through hole resistors also have some drawbacks, such as their large size and more expensive price compared to surface mount counterparts.
