Through hole resistors are a ubiquitous part of many electrical and electronic circuits, so much so that sometimes we don’t give them a second thought. But in order for them to function correctly, the right type of through hole resistor must be employed for the desired application. CMF55320R00BHEA is designed for certain very specific applications, and this article will discuss what those applications are, and how they work.

The CMF55320R00BHEA is a through-hole, high-voltage, precision, metal film resistor. It is compact in size, with a maximum height of 8.0mm and a maximum width of 6.0mm. It is designed specifically for applications in which a high voltage integrity is essential. It is well-suited for electronic circuits that require high-voltage handling, such as power supplies, inverters, rectifiers, and motor drives, as well as in voltage regulators and op amps.

The CMF55320R00BHEA has excellent insulation characteristics and can withstand high temperature and high humidity environments. It is also designed with a special temperature coefficient of resistance (TCR) of ± 20ppm / °C. This ensures that it is able to maintain accurate resistance in a wide range of temperature conditions, ensuring accurate current control.

The CMF55320R00BHEA also features a wide operating voltage range of 200V to 2000V. This makes it suitable for industrial and automotive applications, such as LED lighting and motor control. It is also able to maintain its electrical integrity even in unstable environments, providing reliable and consistent performance.

The CMF55320R00BHEA is constructed with a metal film on a ceramic substrate, which provides excellent stability and max power rating up to 0.5W at 70°C. Additionally, it has low thermal noise, making it suitable for low noise audio and signal processing circuits. Furthermore, its small size offers an advantageous combination of high power handling and small physical size.

The working principle of the CMF55320R00BHEA is quite simple. It works by controlling the current that passes through the resistor, as its resistance is fixed. When voltage is applied across the resistor, current is passed through it. If the current exceeds the rated maximum, the resistor dissipates the excess energy as heat. This limits the current generally coming out of a circuit, and prevents the voltage from rising too high.

The CMF55320R00BHEA is a versatile and reliable through-hole resistor, suitable for a wide range of applications. It is well-suited for many high-voltage applications such as power supplies, inverters, rectifiers, motor drives, voltage regulators, and op amps. It offers excellent insulation and temperature coefficient of resistance, making it capable of maintaining accurate current control even in harsh and unstable environments. It is also designed with an impressive maximum power rating of 0.5W, making it suitable for applications such as LED lighting and motor control. And with its small size, it offers an advantageous combination of high power handling and small physical size.
