Through hole resistors are an integral part of many electronic systems and devices. They ensure that a proper voltage is provided and maintained across the system. Among the many types of resistors, the MF0204FRE52-150K through hole resistor made by Ohmite is one of the most popular. In this article, we will go over its application field and working principle, to understand how and why it is an essential component.

Application field of MF0204FRE52-150K

Observing its model number, we can see that the MF0204FRE52-150K is a through-hole resistor with a value of 150Kohm. This places it in the upper range of power rating, which means it is used in systems that require larger currents and more power. Generally, applications that require lots of power are semiconductor integrated circuits and power transistors, making power limiting and controlling the top priority. Therefore MF0204FRE52-150K through hole resistors are used in these systems due to their high power rating.

The other factor to consider is the lead frame material, which for the MF0204FRE52-150K is a Ni-Fe alloy. This Ni-Fe alloy provides excellent hreatment of both electrical and thermal properties, making it ideal for power transistors which require a stable voltage over a range of temperatures.

To sum it up, the MF0204FRE52-150K through hole resistor is a high power resistor with excellent electrical and thermal properties, making it suitable for use in high power systems.

Working Principle of MF0204FRE52-150K

A resistor is a two terminal passive element that, when connected to a passive circuit, enables the control of the current flowing through it. In the simplest sense, a resistor functions by offering a fixed electrical resistance, measured in Ohms (Ω). This is achieved by generating heat with the electric current, which increases the temperature of the resistor element. As the temperature increases, resistance also increases, which is why they are known as “temperature-dependent”. The current in the resistor is directly proportional to the voltage applied and the resistance of the element, also known as Ohm’s law.

In the case of the MF0204FRE52-150K, the resistance is fixed at 150Kohms. As the temperature of the surrounding environment increases, the resistor will reach its rated power rating. Once the temperature reaches its maximum, the resistance will remain unchanged, despite further increases in temperature. This is useful in high power systems as it allows for more precise control of the voltage across the system, ensuring a stable voltage regardless of the temperature.

The other advantage of the MF0204FRE52-150K is its lead-frame mounting system. This system allows for its quick and secure fitting in its mounted position, ensuring that the resistor remains in the correct position and orientation, while also allowing for easy removal and replacement in the case of a malfunction.

In conclusion, the MF0204FRE52-150K through hole resistor is a high power resistor with improved electrical and thermal properties, making it suitable for high power applications. It is also easy to use and maintain, due to its lead-frame mounting system.
