Introduction

Through Hole Resistors are used in virtually every industrial, automotive, consumer, and electronic equipment, so it\'s essential to understand their application field and working principle.The MF0207JT-52-4K7 is a Through Hole Resistor, developed by U.S. company “Vishay Intertechnology”, and it is suitable for power, automotive and high frequency applications. Its application field ranges from power resistors, power rectifiers, pulse and signal resistors, resistor networks, current/voltage dividers, switching and driver components, and fusing resistors to operational security components, surge protection bypass resistors, and control circuits.This resistor is jam-packed with a variety of features, including an excellent thermal stability, high dissipation power, and high dissipation factor. It is composed of a supplemental high-temperature-resistant material, making certification possible up to the SMD version. The MF0207JT-52-4K7 also offers a broad lead-free portfolio, making it suitable for use in environmentally friendly applications.Working Principle

The inner workings of the MF0207JT-52-4K7 Through Hole Resistor are quite simple. It works on the resistive principle, which states that when a current passes through a resistor, a voltage drop appears across the resistor\'s terminals.The current flowing through a resistor is directly proportional to the voltage applied across it. This is known as Ohm’s law (V=I/R), and it is one of the most fundamental laws in electronic engineering.Based on this principle, the MF0207JT-52-4K7 is designed to provide a fixed resistance of 4K7 ohms, while featuring a very low conducting current of only 0.2A. This resistor is marked either as a “4k7” or “4700”, and it can be used to either limit or regulate current in circuits, or to precisely calculate supply voltage or measure current in an automated system.Design and Features

As far as design is concerned, the MF0207JT-52-4K7 consists of a thick film monolithic body and two leads of solderable material. It is designed to minimize the effects of temperature, moisture, vibration, shock, and chemical attack.Its features include:

• Resistance range of 4K7 ohms
• Power dissipation of 2.5 watts
• Low conducting current of 0.2A
• Excellent performance in both high frequency and high temperature applications
• Ease of integration into operations systems
• Broad lead-free portfolio
• Ease of certification in SMD packages

Safety and Power Ratings

The MF0207JT-52-4K7 Through Hole Resistor is rated for a maximum operating temperature range of -55°C to +150°C. It has a power rating of 2.5 taps when operated at 70°C, and its maximum continuous current is 0.89A.It is imperative to note that when using a Through Hole Resistor, it is necessary to choose a resistor that offers the appropriate power ratings for the application and that the applied current never exceeds the stated working current.Conclusion

The MF0207JT-52-4K7 is a Through Hole Resistor designed to provide excellent performance in high frequency and high temperature applications, while offering a broad lead-free portfolio to ensure compatibility with environmentally friendly applications. It is suitable for power, automotive and high frequency applications, and features a fixed resistance of 4K7 ohms, power dissipation of 2.5 watts, and a conducting current of 0.2A. It is certified up to its SMD version, and is rated for a maximum operating temperature range of -55°C to +150°C.
