Through Hole Resistors are components used to control electrical signals and current. The CFR50SJT-52-300R is an example of such a device, and it is often used in a variety of applications. This article will explain the application field and the working principle of this resistor, as well as other important details.

Applications

The CFR50SJT-52-300R is a through hole resistor, meaning it is designed to be mounted on a printed circuit board with a hole designed in it. This makes it ideal for use in many electronic applications, such as calibration, controlling power supply currents, and in signal conditioning.

The resistor can be used in a variety of operating environments, including humid or wet environments (IP67 rated), which is useful for applications that require moisture protection. The resistor has a maximum working temperature of 85 degrees Celsius and can withstand temperatures up to 200 degrees Celsius intermittently.

Working Principle

The working principle of a through hole resistor is relatively simple. It involves the use of a resistor body, which is then connected to one or more pins at either end. The resistor body has an internal resistance, which is controlled by a series of as many as seven layers of thin films deposited onto the body.

When power is applied to the resistor body, an electric current passes through the body and each of the thin metal film layers. The higher the amount of current, the higher the level of resistance, meaning it will take more power to get the same signal. This helps to regulate the amount of current passing through the resistor at any given time, which makes it suitable for applications that require precise voltage and current regulation.

Stability and Accuracy

The CFR50SJT-52-300R has excellent stability and accuracy. This is due to the seven layers of thin film deposited onto the resistor body, allowing for precise resistance values and tolerance levels. The resistor also has a wide power range from 10 mW up to 1.0 W, which is useful for applications that require high power or wide temperature variation.

Shape and Size

The CFR50SJT-52-300R comes in a variety of shape and sizes, ranging from 0.035 in. to 0.450 in., with a maximum height of 0.180 in. This makes it suitable for applications where size is an important factor, such as for automotive electronics or for hand-held electronics.

Conclusion

The CFR50SJT-52-300R is a through hole resistor that can be used in a wide variety of applications, such as calibration, controlling power supply currents, and signal conditioning. It has excellent stability and accuracy, due to its seven layers of thin film, and it is available in a variety of shapes and sizes. This makes it ideal for any application that requires precise voltage and current regulation.
