Through hole resistors, such as the OL5145E-R52, are common in almost all types of applications and have been used by engineers for years. Generally, these resistors are used in two main types of applications. The first is in power resistors, such as power supply applications, motor control circuits, and switching power supplies. The second is in high-frequency applications, such as RF amplifiers and filters. In either case, these resistors provide necessary electrical protection for the circuit and are designed to withstand high heat.

The OL5145E-R52 is a through hole resistor designed to work in both power resistor and high-frequency application fields. It is rated for a maximum power dissipation of 500 mW and has a maximum voltage rating of 500V. The resistor also boasts a wide operating temperature range of -55°C to +150°C, making it suitable for use in a variety of environments.

At the heart of the OL5145E-R52 is its working principle. This resistor is essentially composed of an oxide-covered pellet of conducting material. This pellet is placed inside a ceramic body, which provides a solid base for the resistor. When a voltage is applied to the pellet, electrons travel through it, a process known as conduction. As the electrons move, they generate heat. The ceramic body then dissipates this heat, protecting the resistor from damage.

The working principle of the OL5145E-R52 also takes into account its power rating. As the voltage and current increase, the heat generated by the pellet will also increase. This, in turn, will cause the power dissipation of the resistor to increase. To protect the resistor from damage, a maximum power rating has been specified. If the power rating is exceeded, then the resistor will be damaged and may be rendered useless.

In addition, the working principle of the OL5145E-R52 also accounts for the wide operating temperature range. Since the ceramic body dissipates the heat generated by the pellet, the operating temperature of the resistor is kept at a safe level. This ensures that the resistor can withstand extreme temperatures without suffering damage.

The OL5145E-R52 is a through hole resistor designed for use in both power resistor and high-frequency applications. Its working principle involves a ceramic body dissipating heat generated by an oxide-covered conducting pellet. It is rated for a maximum power dissipation of 500 mW and has a wide operating temperature range of -55°C to +150°C. By understanding the working principle of this resistor, engineers can design their circuits with the assurance that the OL5145E-R52 will provide the necessary protection.
