Through Hole Resistors

Through hole resistors are an important part of a wide range of applications. They are commonly used for electronic signal filtering, impedance matching, voltage regulation and many more applications. The WHS3-1R5JA1 is a through hole resistor known for its high stability and accuracy and is widely used in various applications. In this article, we will look at its application field and working principle.

Application and Features

The WHS3-1R5JA1 is specifically designed for electronic signal filtering and important applications such as load regulation and power supply stability. It is a high stability and accuracy through hole resistor with a resistance range between 1.5K Ohms to 50K Ohms and a wide temperature range from -20°C to +100°C, with a maximum rating of 0.3W. It is also a temperature stable device with excellent long-term stability and low noise performance. The WHS3-1R5JA1 is an ideal choice for applications in the telecommunications, industrial and consumer products industries.

Working Principle

The WHS3-1R5JA1 is constructed with a combination of metal oxide layers sandwiched between two ceramic materials. The main purpose of this construction is to create a stable resistance value over a range of temperatures. The two ceramic materials, or dielectric materials, prove to be very helpful in achieving higher accuracy levels. This feature of the WHS3-1R5JA1 also helps to achieve a very low temperature coefficient over its temperature range. It also takes advantage of zonal temperature variation so that it can remain stable and accurate in a wide variety of environments.

The WHS3-1R5JA1 works by providing its own internal leakage resistance. This leakage resistance is generated by the metal oxide layers between the two ceramic materials. When a current is applied, the voltage applied across the sensitive element is divided between the two ceramic materials and the resistance value. The voltage applied across the sensitive element is kept constant by the internal leakage resistance. This stable electrical characteristic allows the WHS3-1R5JA1 to maintain its stability and accuracy in most environments.

Conclusion

Through hole resistors like the WHS3-R1R5JA1 are an essential part of a wide range of applications, including communications, industrial and consumer products. The WHS3-1R5JA1 is designed to provide high stability and accuracy over a wide temperature range and offers excellent long-term stability and low noise performance. Its construction also allows it to take advantage of zonal temperature variation, meaning it is able to maintain its stability and accuracy in a variety of applications.
