Through Hole Resistors are a highly reliable line of fixed, variable and trim resistors that are specifically designed for use in through-hole circuit board designs. The FMF3WSFRE73-160K is an example of a through hole resistor that has multiple applications due to its compact size, wide temperature range, and stability over a wide temperature range. This article will explain the various application fields and working principle of the FMF3WSFRE73-160K resistor.

Overview of the FMF3WSFRE73-160K

The FMF3WSFRE73-160K is a through-hole, four-terminal resistor that has been designed to be used in circuits requiring an accurate and repeatable resistance value. The resistor size is approximately 1.57 mm by 3 mm. It has a rated voltage of 160V and is rated for ±1% tolerant values across temperatures that range from -55°C to +155°C. It is also designed to operate from higher temperatures, up to +200°C. It has amaximumpower rating of 0.4 watts with 0.2 watts being typical.

Application Fields

TheFMF3WSFRE73-160K is suitable for use in a variety of applications as its small size and wide temperature range make it well-suited for use in power supplies, DC/DC converters, high temperature electronics, and industrial controls. The small size allows it to be used in densely populated boards with a minimal impact on the overall design, while also providing good heat dissipation which results in a longer life-span for the resistor. Its high temperature rating also allows it to be used in circuits that require extreme environmental conditions without performance degradation.

TheFMF3WSFRE73-160K is also suitable for use in circuits requiring long-term resistance stability. It offers a stable electrical performance over a wide temperature range (+20°C to +125°C) with a maximum tolerance of ±1%. This is especially useful when designing circuits requiring accuracy over a long-term period as the resistor will remain stable during prolonged use.

Working Principle

The FMF3WSFRE73-160K resistor uses two main components to achieve its resistance values—the material of the resistor itself and its size. The material used is a combination of metals and alloys that have been carefully selected to provide the desired total resistance value and temperature stability needed for a particular application. The resistor size is determined by the total resistance required and the temperature stability needed, both of which can vary depending on the application.

The total resistance value of the resistor is created through the combination of the resistor material and its size. As the size of the resistor increases, the resistance also increases accordingly. This is because the apparent surface area of the resistor is larger, resulting in more resistance. On the other hand, if the size of the resistor decreases, the resistance decreases accordingly as the apparent surface area of the resistor is smaller, resulting in less resistance.

The temperature stability of the resistor is also vitally important as fluctuations in temperature can cause the resistance value to shift. The FMF3WSFRE73-160K is designed to be highly temperature stable in order to provide reliable and consistent performance. This is accomplished by carefully selecting a combination of metals and alloys used in the resistor material that have low coefficient of thermal resistance. This results in resistors that are accurate and stable across a wide range of temperatures.

Conclusion

TheFMF3WSFRE73-160K is a highly reliable through hole resistor designed for use in circuit board designs requiring an accurate and stable resistance value. Its small size, wide temperature range, and long-term stability across a wide temperature range make it suitable for use in a variety of applications such as power supplies, DC/DC converters, high temperature electronics, and industrial controls. The working principle of the resistor is based on the combination of its material and size, ultimately resulting in a highly temperature stable resistor that is able to provide accurate and consistent performance over time.
