Through Hole Resistors are increasingly becoming popular among engineers and technicians due to their convenience, affordability and the ease of installation. The OL1215E-R52 is no exception, and its application field and working principle should be understood by anyone installing or using them. This article will provide an overview of the OL1215E-R52 resistor, explaining its application field and working principle.

Application Field

The OL1215E-R52 resistor is a through hole resistor that is typically used in applications such as circuits with extremely high voltages, transistors, and as a voltage-dropping resistor in linear power supplies or in voltage regulation applications. It is also used as a current-limiting resistor in applications such as flashing LEDs, and in digital or analog circuits that require precise precision. This resistor is available in a variety of wattages, including 1/4W, 1/2W, 1W and 2W, as well as in a range of resistance values, from 1 ohm to 4.7 M ohms.

Working Principle

The working principle of the OL1215E-R52 resistor is quite straightforward. This resistor is composed of two resistors connected in series: one resistor with a resistance value of 10 ohms (R1) and one with a resistance value of 5.2 ohms (R2). When connected to a power source, the resistor dissipates power and reduces the voltage or current, depending on the resistance values selected by the user. The power dissipation is determined by the product of the voltages across each resistor, multiplied by the current that passes through them.

For example, if the power supply voltage is 20V and current is 5mA, then the power dissipation is (20V x 5mA)/(10 ohms + 5.2 ohms) = 1W. This indicates that the resistor can safely dissipate up to 1W of power. In order to safely dissipate more power, the resistor must be adapted for higher wattage. In this case, the user must select a resistor with higher wattage ratings.

Conclusion

The OL1215E-R52 is a Through Hole Resistor that has a wide range of applications, from voltage regulation circuits, to flashing LEDs and precision analog and digital circuits. It offers good durability, stability, and reliability, and can handle up to 1W of power dissipation. By understanding the application field and working principle of this resistor, users can easily select the right rating and resistance values to meet their needs.
