Through Hole Resistors refer to resistors that are physically larger than their SMD cousins and require physical insertion into a circuit board. In this category are several specific resistor types that differ in configuration and form. Two of the most popular types of through hole resistors are the MF0204FRE52-4K99. Understanding the application field and working principle of these resistors can help us work with them more efficiently, get better performance, and extend the life of circuitry and other components.

MF0204FRE52-4K99 Application Field

MF0204FRE52-4K99 are typically used in applications where high-power dissipation with a low thermal resistance is required. These resistors have a maximum power rating of 1 Watt, and they are designed for either surface-mount or through hole mounting. As their name implies, the packaging type for the MF0204FRE52-4K99 is non-hermetic. The resistors feature a tight tolerance of ±1%, ensuring a high level of accuracy for the resistance values. The maximum operating temperature range of these resistors is -55°C to +125°C.

The MF0204FRE52-4K99 resistors have a low thermal resistance due to their unique design features. They consist of a ceramic substrate with a resistance element in the center. This element is surrounded by a matrix that provides additional electrical insulation and helps to dissipate heat. Additionally, the resistor is sealed in place with a special epoxy to protect it from environmental factors such as moisture, dirt, and other contaminants.

Due to their low thermal resistance and high power rating, the MF0204FRE52-4K99 resistors are ideal for use in many electronic applications. These include power supplies, inverters, switching power supplies, voltage regulators, motor drive circuits, and automotive electronics. They can also be used in high-temperature and high-speed digital circuits. Additionally, they can be found in circuits where temperature stability and accuracy are critical.

MF0204FRE52-4K99 Working Principle

The working principle of the MF0204FRE52-4K99 resistors is based on ohm\'s law which states that the current passing through an electric circuit is directly proportional to the voltage applied. The resistors feature a predetermined resistance value and when a voltage is applied across them, they will dissipate heat equal to the voltage multiplied by the current (I =V/R). This heat is then dissipated into the surrounding environment via a heat sink or with the help of a fan.

The resistance element of the resistors is made of an alloy that has a higher melting temperature than that of other alloys. This ensures that the resistors can withstand higher temperatures without sustaining physical damage. The resistors are also sealed with a special epoxy that protects them from environmental contaminants, making them highly reliable.

In terms of accuracy, the resistors have a tight tolerance of ±1%. This means that any resistors made with the same value will differ by no more than +/- 1%. This accuracy ensures that the final product will operate as intended, even in the most demanding applications.

In summary, the MF0204FRE52-4K99 is a through hole resistor that is designed to offer high-power dissipation with a low thermal resistance. These resistors are ideal for use in a variety of electronic applications due to their tight tolerance of±1%, making them highly reliable and accurate. Furthermore, their sealed construction makes them resistant to environmental contaminants, giving them improved durability.
