Through Hole Resistors are a very important component in electronics, as they provide a range of resistance values allowing for precise adjustments and control of current in circuits. One such type of resistor is the OL1025E-R52, which offers a range of resistances from 0.1Ω to 120KΩ. This article will look at both the application field and working principle of the OL1025E-R52.

Application Field

The OL1025E-R52 is designed for use in high reliability applications due to its accurate long-term stability and wide operating temperature range. It has a power rating of 1/4 W, which makes it suitable for use in circuits running at up to 625 mA. Additionally, the OL1025E-R52 has a wide range of tolerances, ranging from ±10%, ±20% to ±50%, making it suitable for most applications. Another advantage of the OL1025E-R52 is its small size, with dimensions of just 0.45" x 0.28" x 0.2" (1.14 cm x 0.72 cm x 0.51 cm), making it suitable for compact designs.

As such, the OL1025E-R52 is suitable for a wide range of uses, especially within high voltage and power supply circuits, audio amplifiers, potentiometers, motor control, switching power supplies, DC-DC converters and other general electronics.

Working Principle

The OL1025E-R52 is a carbon film resistor, a type of resistor created by coating a ceramic core with a thin layer of carbon. The resistor is composed of two conductive metal plates spaced apart, with the ceramic core and carbon layer between them. The carbon layer adds resistance to the circuit, with the thickness of the carbon layer varying depending on the resistance value required.

When a voltage is applied across the two metal plates, the current will flow though the carbon layer, with the resistance this layer provides limiting the amount of current. The higher the resistance value of the resistor, the less current will flow through it, thus producing a lower output voltage.

The OL1025E-R52 is an ideal choice for use in high voltage and power supply circuits, as it provides accurate and stable resistance values that won\'t vary over time. Additionally, its small size and wide range of tolerances makes it highly suitable for use in many different applications.
