Through Hole Resistors: RNMF14FTD7R87 Application Field and Working Principle

Through hole resistors are a type of resistors that are mounted on printed circuit boards for the purpose of providing electrical circuit protection and heat dissipation. The RNMF14FTD7R87 resistor is a powerful heat dissipation and protection tool. This article will discuss the application field and working principle of this resistor.

Application Field

The RNMF14FTD7R87 resistor has a variety of applications. It is primarily used to provide over-current protection for printed circuit boards. This includes heat dissipation, voltage and current regulation, and other control functions. The resistor can also be used for load management, power conversion, and signal conversion. It is suitable for high density electrical systems and is used in a variety of industries such as power conversion, industrial automation, and home appliance control.

Working Principle

The RNMF14FTD7R87 resistor works by regulating the current flow through the circuit. It does this by dissipating energy from the circuit in the form of heat. As the current gets stronger, the resistor heats up and dissipates more energy. This affects the voltage and current, thus regulating the amount of power supplied.The resistor works on a principle known as the ‘Peltier effect’. This is where two separate metals have different electrical potentials across them. This creates an electric field and the voltage propagates through the resistor, thus controlling the current.

Advantages

The main advantages of the RNMF14FTD7R87 resistor include its small size, low cost, and high temperature tolerance. It can be easily installed on a printed circuit board without soldering, thus making it ideal for quick repairs and replacements. The resistor is also resistant to corrosion and vibration. This makes it suitable for use in harsh environments.

Disadvantages

There are a few disadvantages of the RNMF14FTD7R87 resistor. For one, it is not as reliable as other types of resistors. It is also prone to temperature instability and can be easily damaged in certain conditions.Despite its disadvantages, the RNMF14FTD7R87 resistor is an effective heat dissipater and protection tool. Its small size and affordability make it a popular choice for industrial applications. It is also easy to install and maintain. With proper installation and maintenance, it can help in providing electrical circuit protection for years.
