The Through Hole Resistors are resistors that are able to provide a high degree of resistance against opposing electrical or electronic signals. This type of resistor is one of the most important components found in circuits. In this article, we will take a look at the application field and working principle of the 43F25R resistor.

The 43F25R resistor is a through-hole resistor typically used in signal conditioning and measurement applications. Its design is based on an encased metal-oxide film or ceramic resistor. Since the resistor is made out of metal-oxide film, it is able to protect against vibrations, impact, and temperature or humidity extremes. It is also known for being a non-inductive device, meaning that it does not produce inductive fields that could interfere with signals in the circuit.

The 43F25R resistor has a wide range of applications, including industrial, audio, automotive, HVAC systems, medical, and defense-related applications. The resistor is typically used in applications where precise measurement and control of electric or electronic signals is required. For instance, it can be used when a precise voltage reference is required in order to measure a variety of other signals accurately. Additionally, it can be used when providing regulated and isolated power supplies and when controlling current levels in various applications.

The 43F25R resistor works using Ohm’s law, where the current going through a resistor is equal to the voltage across it divided by its resistance value. On the resistor, you will find a series of markings that indicate the value of its resistance. Typically, the markings will look like this: 3F25R or 43F25R, where the first two characters indicate the resistance value and the last two characters indicate the tolerance of the resistor. For this particular resistor, the resistance would be 43 Ohms with a tolerance of 25%. There are also different types of resistors in this series, such as the 43F50R, which has a resistance value of 43 Ohms but with a tolerance of 50%.

The 43F25R resistor is able to handle up to 10W of power and can operate in temperatures between -55°C and + 260°C. It is important to point out that it is not suitable for high frequency applications, as it is typically limited to a few mega-Hertz. Additionally, the 43F25R resistor is typically soldered to a printed circuit board and can be removed and resoldered for maintenance or repair.

In conclusion, the 43F25R resistor is a through-hole resistor typically used in signal conditioning and measurement applications. It is made out of metal-oxide film, which is able to protect against damages caused by vibrations, impacts, or temperature or humidity extremes. It also works using Ohm’s law and can handle up to 10W of power. Although it is not suitable for high frequency applications, the 43F25R resistor is able to handle a wide range of applications, such as industrial, audio, automotive, HVAC systems, medical, and defence-related applications.
