Introduction to Through Hole Resistors and OJ2415E-R52

Through hole resistors are widely used in electrical circuits due to their simplicity and low cost. Used in applications such as power supplies, circuit protection and filtering, these components provide a stable, predictable resistance value, enabling precise resistance adjustment and system calibration.An example of a through-hole resistor is the OJ2415E-R52, an axial leaded resistor designed to meet the requirements of various high-reliability applications. This resistor is a powerful and efficient solution for use in environments where normal resistors are not suitable, such as high vibration, high temperature, and shock applications. Additionally, the OJ2415E-R52 can be used in circuits where current loads are demanding, such as when power levels exceed 200 Watts.The Features and Benefits of Through Hole Resistors

Through-hole resistors are designed for applications that require robust electrical performance and reliable operation. These resistors offer the following features and benefits:

• High power rating – Through hole resistors are rated for higher wattage levels than comparable surface mount resistors, up to 200 watts for the OJ2415E-R52. This makes them ideal for use in high power or current applications.
• Fast response time – Through-hole resistors also have faster response times than surface mount components, which allows them to better handle sudden changes in load or current.
• Improved safety – The through-hole design allows heat to dissipate more effectively, keeping components cooled more efficiently and reducing the risk of damage.
• High reliability – Through-hole resistors are tested to ensure they will stand up to demanding environments and conditions, providing reliable operation over long periods of time.
• Broad temperature range– The OJ2415E-R52 is rated for use at temperatures ranging from -55°C to +150°C. This makes it a good choice for applications in extreme temperature environments.

The Working Principle of the OJ2415E-R52

The OJ2415E-R52 resistor works on the same basic principle as other resistors: an electrical current passes through a resistance material, causing a voltage drop across the resistor. The resistor’s resistance is determined by the ratio of the voltage drop across it to the current flowing through it, also called its impedance.The OJ2415E-R52 is a high-power, high reliability resistor. Its construction is designed to ensure maximum heat dissipation and reliability in high power applications. Its epoxy coated leads and iron alloy core can handle high-current loads while allowing heat to dissipate quickly. The resistor is also housed in a rugged, UL-approved package.Applications for the OJ2415E-R52

The OJ2415E-R52 is designed for use in a variety of high-reliability applications that require a high power rating and robust electrical performance. It is ideal for power supplies, circuit protections, and filtration, as well as applications exposed to high levels of vibration, shock, and temperature.The resistor is also suitable for use in professional communications and device systems, such as audio and video systems, signal transmission systems, automotive electronics, and process control systems. Additionally, it can be used in aircraft, military, and industrial environments that require resilient electronic components.In conclusion, through-hole resistors, such as the OJ2415E-R52, provide a reliable resistance solution for a variety of demanding applications. They offer a higher wattage rating, fast response time, improved safety, and a wide temperature range. They also possess a robust construction and design to ensure they remain reliable in punishing conditions.
