Through Hole Resistors have a variety applications, ranging from simple signal processing to sophisticated power control. Among these is the H847KFDA, which is a specific type of resistor that is designed mainly for the purpose of safety and high temperature stability. This article will discuss how the H847KFDA fits into the larger world of through hole resistors, its unique characteristics, and its working principle.

The H847KFDA is characterized as an axial lead (through hole) resistor, meaning it can be mounted either through holes or soldered onto a circuit board. The resistor has an epoxy-coated insulating tube and a resistance value of 4.7KΩ. It is also equipped with a sophisticated copper-plated element structure that helps to ensure high-temperature stability, up to a maximum of 250°C in some cases. Furthermore, the resistor is marked with a variety of features to indicate the type, material, and performance level, such as a resistance code, a ring trace, or a high capacity bar code.

The unique features of the H847KFDA make it an ideal candidate for through-hole resistor applications. This type of resistor is often used in industrial, automotive, and medical applications that require a high level of safety and high temperature stability. For example, the H847KFDA can be used for load current sensing, electrical noise isolation, and current limiting in applications such as motor control or lighting systems. It can also be used as a thermal fuse in safety circuits that require short-circuit protection. Additionally, it can be used in automotive applications that involve measuring boost pressure, controlling fuel injection, and regulating engine speed.

In terms of working principle, the H847KFDA utilizes a negative temperature coefficient (NTC) thermistor. The NTC thermistor is a special type of resistor that has a negative resistance response to increases in temperature. As the temperature rises, the resistance value of the resistor decreases, and vice versa. In the case of the H847KFDA, the resistor is sensitive to changes in temperature and is able to maintain a consistent resistance value over a wide temperature range.

The H847KFDA also utilizes a unique copper-plated element structure that allows it to be used in high-temperature applications up to 250°C. In addition, the resistor is designed with a low self-inductance that ensures low levels of noise interference. This allows the resistor to be used in high-frequency applications such as telecommunication and audio/video systems.

Overall, the H847KFDA is a specialized type of through-hole resistor that is characterized by its high temperature stability, safety features, and unique copper-plated element structure. It is most often used in industrial, automotive, and medical applications that require a high level of safety and/or temperature stability. Furthermore, the H847KFDA utilizes a NTC thermistor working principle that allows it to maintain a consistent resistance value over a wide temperature range. This makes it a highly versatile and dependable resistor for many types of applications.
