Through Hole Resistors - MR5FTR200 Application Field and Working Principle

Through hole resistors, also known as leaded resistors, are passive electrical components used in a variety of applications, notably in circuit boards and other electronics systems. Lead-based resistors can be used in both high- and low-current situations, due to their low volume and prohibitively low resistance values. A commonly used leaded resistor is the MR5FTR200, a through-hole resistor known for its low resistance values, precision, reliability, and affordability.

Application Field

The MR5FTR200, is used extensively in a broad range of industries, including medical, aerospace, and automotive. Its resistance values vary from 0.7 to 10 kΩ, making it suitable for a wide variety of applications. Common uses for the MR5FTR200 include voltage regulation, decoupling, and signal control.

The main application field of the MR5FTR200 is related to automotive systems. This through-hole resistor can withstand temperatures ranging from -40 to +125℃ and is therefore the ideal component for fuel injection systems, airbag systems, brakes, and door locks.

Working Principle

The MR5FTR200 is a through-hole resistor with an extremely low on-resistance rating of 0.2Ω to 10 kΩ. The resistor is made up of a copper housing filled with carbon pellets. These pellets act as the resistive element, and are arranged in a spiral pattern with specific resistance values. This design has the added bonus of providing increased heat dissipation, allowing it to handle high-current applications.

The resistor is connected through two terminals, each with its own resistance value. Voltage is applied to one terminal, while the other terminal is connected to ground. As the voltage passes through the resistor, it is reduced by the resistance value of the component. This is known as Ohm’s law, and is the basis of the resistor’s working principle.

The MR5FTR200 is a reliable and robust device, designed to withstand a wide range of temperatures and currents. Its low temperature coefficient of resistance ensures the resistor maintains its resistance at varying temperatures, making it an invaluable component in numerous industries.

Conclusion

The MR5FTR200 is a widely used lead-based resistor, found in many applications. It has an extremely low resistance rating of 0.2Ω to 10 kΩ, and is designed to withstand temperatures ranging from -40 to +125℃. It is often used in automotive systems, and is also suitable for voltage regulation, decoupling, and signal control. Its low temperature coefficient of resistance ensures that its resistance remains consistent at varying temperatures, making it a reliable and robust device.
