Introduction to Through Hole Resistors and their application and principles

Through Hole Resistors are a type of electric resistor typically featuring leads or terminals for connecting to a circuit board. These Resistors are commonly used for electronic equipment and appliances, and they can be found in a wide variety of settings. They are deployed in numerous applications including voltage dividing circuits, power supplies, automotive circuits, and high voltage circuits to name a few. In this article we will focus on one particular type of Through Hole resistor, specifically the PPN360FT-73-10R, and will discuss its application field and working principle.

What is the PPN360FT-73-10R?

The PPN360FT-73-10R is a through hole, radial leaded, top adjusted, ceramic-based, single-layer resistor. It features a power rating of 0.25W, low temperature coefficient of +3ppm/℃, and high tracking voltage of 5.5KV. The resistor has a composition which includes a ceramic body, glass electrodes, and a solderable coating. It is used in high-precision applications such as circuit boards, as an integral part of power supplies, and it can be found in automotive, medical, lighting, and many other applications.

Application Field

The PPN360FT-73-10R is a versatile resistor which is suitable for use in a variety of applications. In the power supply field, it is used in direct current-to-direct current (DC-DC) converters for the control of circuit output or feedback voltage. This particular component also finds use in voltage dividing circuits, which are used to create a fixed voltage or current at a particular point in a circuit. Furthermore, it is used in automotive circuits which require reliable performance over very low and very high temperature ranges.

The PPN360FT-73-10R is also widely used in medical and laboratory equipment, as well as in lighting and audio systems. It is an ideal choice for applications where the performance of the resistor must withstand high power levels or high operating temperatures. Due to its high reliability and precise temperature coefficient, it is also often used for in-circuit-test (ICT) applications.

Working Principle

The working principle behind the PPN360FT-73-10R is simple yet effective. The component works by using a resistor core, which is a metallic or ceramic pellet, to provide electrical resistance. As electricity passes through the resistor core, it is impeded or slowed by the resistance of the core, thereby allowing the component to regulate the flow of electricity and voltage. Different materials and shapes of the resistor core can result in different levels of electrical resistance and hence, different electrical resistance values or wattages.

The resistor core of the PPN360FT-73-10R is made from a ceramic material, which is capable of providing reliable performance over a wide range of temperatures. The ceramic material is also highly resistant to vibrations, making it ideal for use in demanding applications. The component also features a glass electrode which is designed to endure high operating voltages. The combination of these two components, the ceramic resistor core and glass electrode, provide excellent electrical insulation.

Conclusion

In conclusion, the PPN360FT-73-10R is a highly versatile and reliable through hole resistor which is suitable for many different application fields. This component features a ceramic resistor core and glass electrode for reliable performance in demanding conditions. It is capable of providing precise voltage regulation, efficient power management, and long-term stability in high-performance, high-precision circuit designs.
