Through Hole Resistors

OL3345E-R52 is one of the many through-hole resistors available on the market today. While modern surface-mount resistors are becoming more and more popular, there are still many applications for which through-hole resistors are preferred. In this article, we will discuss the application field and working principle of OL3345E-R52.

It has a unique design that makes it well-suited to these applications. The features of OL3345E-R52 include a high operating temperature range of -55°C to +200°C, a wide resistance range of 0.2Ω to 33KΩ, and a low expected maximum voltage of 250V. The resistor is also RoHS compliant, and it has a short thermal time constant of 4 seconds.

Due to its robust design and high reliability, OL3345E-R52 is suitable for use in both commercial and industrial applications, such as automotive, telecom, power electronics, consumer electronics, instrumentation, and military applications.

Working Principle

The working principle of through-hole resistors is essentially the same as that of surface-mount resistors. The resistor consists of a metal conductor placed inside an insulating layer. When an electrical current is passed through the metal conductor, it creates a resistance that dissipates some of the electrical energy as heat. This heat is then released into the surrounding environment.

The difference between through-hole and surface-mount resistors is in the way they are constructed. Through-hole resistors have their leads (metal conductor) extended through the circuit board, while surface-mount resistors are simply seated on top of the circuit board. The extended leads of through-hole resistors provide better support and reliability, which is why they are often preferred for high-temperature and high-reliability applications.

Also, OL3345E-R52 has a unique construction that helps to improve the reliability of the component. The resistor is made with a low temperature co-efficient material, which helps to reduce the effects of temperature shifts on the resistor\'s performance. Additionally, the resistor also features a specialised thermal design which helps to ensure that the resistor remains operational even in extreme conditions.

Conclusion

In conclusion, OL3345E-R52 is a through-hole resistor that is specifically designed for high-temperature, high-reliability applications. Its robust design and specialised construction ensure that the resistor can handle extreme conditions without compromising on performance. Furthermore, its wide resistance range, high operating temperature, and short thermal time constant make it the perfect choice for a wide range of commercial and industrial applications.
