MFR-25FRE52-2M21

Through Hole Resistors are components designed to provide a controlled resistance to a circuit. MFR-25FRE52-2M21 is a type of through hole resistors typically used in surface mount applications. The main purpose of the MFR-25FRE52-2M21 is to act as a current limiting device in order to protect sensitive components in the circuit. The resistor offers a wide range of applications due to its power rating of 25W.

The MFR-25FRE52-2M21 has a default resistance value of 2mOhms. This type of resistor is capable of operating at up to 500V with a 2% tolerance. It has a lead size of 2mm and a pitch of 5mm. This makes it suitable for use on a wide variety of surface mount applications.

The MFR-25FRE52-2M21 is typically used in power circuits, high voltage circuits, and parasitic diode protection circuits. It can also be used for overcurrent and thermal cutoff protection. This type of resistor can also be used in series circuits for impedance matching. Its wide resistance tolerance gives it the ability to be used in most circuits without needing to be adjusted.

MFR-25FRE52-2M21 is made up of several key components including a ceramic dielectric, a resistive element, and a series of soldering terminals. The ceramic dielectric is what provides the electrical insulation between the resistive elements and the terminals. The resistive element is what holds the resistance and it is usually made of a metal film or ceramic composition. Finally, the soldering terminals are what allows the resistor to be connected to the circuit board.

The working principle of MFR-25FRE52-2M21 is simple, when a current is passed through the resistive element, a voltage is produced across it. This voltage is inversely proportional to the resistance. So the higher the resistance, the lower the voltage across the resistor and vice versa. The resistor then acts as a current limiting device that prevents high voltage spikes and prevents sensitive components from being destroyed.

In summation, the MFR-25FRE52-2M21 is a type of through hole resistor typically used in power circuits, high voltage circuits, parasitic diode protection circuits, as well as overcurrent and thermal cutoff protection. The resistor operates on a simple principle, which is that a voltage is produced across the resistor that is proportional to the resistance. This resistor has a power rating of 25W, a resistance value of 2mOhms, and a 2% tolerance. It also has a lead size of 2mm and a pitch of 5mm making it suitable for use in surface mount applications.
