Through Hole Resistors are essential building blocks of electrical circuits. The CMF55169R00BHEB is a type of through hole resistor that is particularly useful for high voltage and high power conditions. In this article, we will explore its application field and working principle.

The CMF55169R00BHEB is a thick-film, surface-mount resistive device designed to operate in temperatures ranging from -55°C to +125°C. It is available in a variety of sizes and resistance values with five resistance ratings from 10kΩ to 100kΩ. It is suitable for applications in high-power, high-voltage, and high-frequency environments. Because of its high power capacity and long life, it is used in many applications such as power supplies, medical devices, inverters, motor drives, military, aerospace, and instrumentation.

The CMF55169R00BHEB is a three-terminal resistor constructed with a thin film of ceramic-protected metal oxide. It is a fixed resistor with terminals consisting of three pins that are electrically isolated from each other. The three pins are the Positive Pin, the Negative Pin, and the Shield Pin. The Positive Pin and the Negative Pin are separated by a sacrificial oxide layer and a dielectric layer. The Shield Pin is connected to the ceramic substrate and connected to a bulk conducting material.

The CMF55169R00BHEB has an overall tolerance of ±2% and a rated power of 0.25W, which ensures it has greater power handling capabilities than many other through hole resistors. It is also specified as having a temperature coefficient of resistance (TCR) of 250ppm/°C. The rated voltage for the CMF55169R00BHEB is 50V, with an operating voltage of 80V. It is suitable for applications requiring high-akm resistance.

The working principle of the CMF55169R00BHEB is relatively simple. When an electrical current passes through the resistive element, its resistance creates a voltage drop, or potential difference, across the circuit. This voltage drop is proportional to the current and the resistance of the element. By understanding both the current and the resistance, it is possible to calculate the voltage drop.

The CMF55169R00BHEB is highly reliable and is used in a broad range of applications. Its excellent operating temperature range and high tolerance makes it ideal for many applications where high reliability and accuracy are essential. Additionally, this part provides very low noise levels and is able to withstand high voltages and currents, making it suitable for use in high-power systems. It is also used in high-frequency applications where its low inductance and small size make it an excellent choice.

In conclusion, the CMF55169R00BHEB is a through hole resistor that is particularly useful in high voltage and high power conditions. Its operating temperature range and high tolerance make it suitable for many applications that require high reliability and accuracy. Its low noise levels and small size make it suitable for use in high-power and high-frequency applications as well, making it a highly reliable and versatile part.
