Through Hole Resistors

Through hole resistors are a widely used component in the electronics industry. The RN65D4300FRE6 is a through hole resistor specifically manufactured by Samsung Semiconductor Co. that has many features and applications. This article will provide an overview of the RN65D4300FRE6’s application field and working principle.

Applications

The RN65D4300FRE6 is a through hole resistor that is typically used in a variety of electronic circuit boards. It has a power rating of 4.4W, an operating temperature range of -40°C to +125°C, and is available in a range of resistance values from 1K to 10K. It is ideal for use in computers, LCD monitors, automotive systems, power supplies, and other electronic systems. Additionally, the resistor is AEC-Q200 qualified, so it is suitable for use in automotive systems.

Design

The RN65D4300FRE6 is a surface mount resistor made with a metal oxide varistor (MOV) construction. The resistor is constructed using a high temperature firesetting process. This process helps to ensure a reliable electrical contact by fusing the metallic spark gap contacts to the ceramic substrate and connecting them through the contact pins. The resistor has a full molded package structure, and is constructed using flame retardant resin and organic tape. This design provides a superior heat dissipation rate and superior vibration resistance.

Working Principle

The RN65D4300FRE6 features a high-voltage MOV based circuit for protection against voltage surges. The MOV works by providing an overvoltage disconnect feature. When an overvoltage is applied, the MOV dissipates the extra current in the form of heat. The resistor is able to handle high surge currents of up to 8KA without damage due to its low-leakage construction and high thermal dissipation.

The RN65D4300FRE6 also has an unique circuit design feature that allows it to function as a self-healing mechanism. When the resistor experiences an overvoltage, the MOV will switch on and dissipate the energy of the overvoltage. The circuit will then reset itself and it will start functioning as normal. This self-healing mechanism helps to ensure that the resistor is protected against circuit damage in the event of an overvoltage.

Conclusion

The RN65D4300FRE6 is a through hole resistor that is ideal for use in a variety of electronic circuit boards. It has a high surge current rating and a self-healing mechanism, making it suitable for use in a variety of applications. This article has provided a brief overview of the RN65D4300FRE6’s application field and working principle.
