Through Hole Resistors are primarily used in a variety of electronic applications for their ability to limit the flow of current and maintain a steady voltage. The OL3015E-R52 Through Hole Resistor is an excellent example of a device designed for these purposes. It is a compact package containing three integral parts—a resistor, a terminal, and a carrier. By understanding the application field and working principle of this resistor, one can better utilize this device and increase system performance and reliability.

Application Field of the OL3015E-R52 Through Hole Resistor

The OL3015E-R52 is primarily used in industrial and automotive applications, such as automotive in-vehicle networks, motor drives, controllers, and power inverters. This device is rated to handle up to 45A of current and provides excellent frequency response in the range of 200kHz to 10MHz. This makes it an ideal choice for use in high-frequency motor control circuits.

In addition, the OL3015E-R52 is also well suited for power circuit applications, such as power switching and control. This device can be used in a variety of applications, including ac/dc and dimming control, power factor correction, and power limiting. Additionally, this resistor is well suited for use in isolated input/output stages, as well as motor control stages. This makes it an excellent choice for applications such as factory automation and equipment control.

Working Principle of the OL3015E-R52 Through Hole Resistor

The OL3015E-R52 utilizes a three-terminal configuration in order to provide superior mechanical stability. The central terminal is designed to couple the two end terminals. The connection between the end terminals is typically achieved using either solder or crimp technology. The connection is then sealed with a coating, providing a moisture-proof connection.

The device uses a mechanical thermal resistance element to dissipate heat generated from the resistor. This thermal resistance element is designed to transfer heat away from the center terminal and evenly distribute it to two end terminals, which then dissipates the heat into the environment. Additionally, a special shield is placed around the device to further reduce the amount of heat generated. This helps to ensure optimal performance and reliability.

Additionally, the OL3015E-R52 utilizes a temperature compensating delta-dimerization technique which helps to adjust the device’s characteristics according to changes in temperature. This technique also helps to prevent false triggering of the device caused by temperature fluctuations.

Finally, the OL3015E-R52 contains several other features which further improve system performance and reliability. These features include a gas-filled metal oxide varistor which helps provide protection against surge voltages, as well as offset voltage blocking elements which help reduce chip and board-level noise. Additionally, the device also contains a hermetically sealed enclosure which helps to protect against external dust and moisture.

Conclusion

The OL3015E-R52 Through Hole Resistor is an ideal choice for a number of industrial and automotive applications. The device has a three-terminal configuration and is rated to handle up to 45A of current. Additionally, the device also contains several features which help to improve system performance and reliability, such as a mechanical thermal resistance element, a temperature-compensating delta-dimerization technique, and offset voltage blocking elements. This makes the OL3015E-R52 a perfect choice for various power circuit applications.
