Through Hole Resistors

Through hole resistors, once the dominant technology for resistors in electronics, has seen a decline in its popularity relative to its surface mount counterpart. However, due to certain benefits that it has over surface mount, like a greater ability to dissipate heat, it has still retained its importance in the electronics industry. One such through hole resistor is the Y09590R10000F9L, which is primarily used in high-power applications that require both high-voltage and high-temperature capability. This article will discuss the key features of this resistor as well as its applications and working principle.

Key Features

The Y09590R10000F9L is a ceramic core through hole resistor which has high temperature capability and a wide resistance range of 1 to 10,000 ohms. It has a moisture resistance rating of 135°C, making it suitable for use in high temperature and humid environments. Additionally, it has an insulation resistance of > 1000 ohm/cm, making it highly resistant to breakdown under current. The resistor has a Tolerance of ±5% and a Power Rating of 30W. Its dimensions are 17.6 x 12.8mm, which allows it to fit into most standard through hole applications.

Applications

The Y09590R10000F9L is primarily used in high power applications, such as welding robot fixtures, current sensors, power supplies, adjustable power supplies, DC motor controllers, and other electronic equipment that require high voltage and temperature operation. Additionally, due to its wide resistance range and high insulation resistance rating, it can be used to protect electronic devices from voltage surges. Furthermore, it is also used in power supplies and circuits to provide a safe and consistent current to other components.

Working Principle

At the core, all resistors operate in the same way – they provide resistance to the current passing through them. The Y09590R10000F9L does so by having a ceramic core which has a fixed resistance. The amount of resistance is determined by the diameter and length of the ceramic core. Additionally, it also features a dielectric which serves to insulate the conductor from the ceramic core and protect it from mechanical and electrical damage. As the current flows through the resistor, a voltage drop is produced which is equal to the resistance multiplied by the current. This phenomenon is known as Ohm’s law.

The amount of power dissipated by a resistor is determined by the square of the current flowing through it. To reduce the risk of damage caused by the heat generated, it has a high temperature resistance of 135°C and a power rating of 30W. It also has a high insulation resistance value of > 1000 ohm/cm, which serves to keep its contents isolated from the current, and therefore keeps its resistance value constant.

In conclusion, the Y09590R10000F9L is a ceramic core through hole resistor which has high temperature and voltage capabilities. Its wide resistance range, combined with its high insulation resistance rating, makes it suitable for high power applications. Additionally, its size and robust structure make it a good fit for through hole applications. Finally, its working principle is based on the behavior of electricity passing through a resistor, which produces a voltage drop – a phenomenon known as Ohm’s law.
