Through Hole Resistors, such as those of the MFR-25FTF52-3M9 variety, offer many advantages in a wide range of applications. These resistors offer higher power dissipation capabilities, longer temperature cycling capabilities, and better electrical insulation characteristics compared to other resistor technologies.
The main application of the MFR-25FTF52-3M9 Through Hole Resistor is for high voltage protection, bypassing, or filtering circuits. It is most commonly used in substation, residential, and commercial electrical installations, where these resistors must operate reliably under heavy load conditions. The great power dissipation and thermal-cycling capabilities of the MFR-25FTF52-3M9 make it suitable for highly reliable protective installations.
The MFR-25FTF52-3M9 Through Hole Resistor has a resistance value of 3M9, which is equivalent to 3.9 kilohms. It is constructed using a combination of wire-wound elements and a ceramic substrate. Its temperature rating range is -40 to +125 degrees Celsius, which gives it a very wide operating temperature range.
The working principle of the MFR-25FTF52-3M9 Through Hole Resistor is relatively straightforward. Electric current passes through the resistor element, which is the wire-wound part. This causes the temperature within the resistor body to rise and, as resistance increases with temperature, the amount of current passing through the resistor is reduced. Therefore, the MFR-25FTF52-3M9 effectively regulates the output current in the circuits it’s installed in.
The resistors are usually installed on plugs or other printed circuit boards for easy installation. This makes it highly suitable for ready-made applications and quick installations. The ceramic substrate is highly insulating and helps to prevent short circuits or overheating, further enhancing the reliability of the component.
The MFR-25FTF52-3M9 Through Hole Resistor is a highly reliable component and a good choice whenever long-term or heavy-duty electrical protection is required. Its wide temperature range makes it suitable for a variety of applications, from street lighting to industrial heating and ventilation systems. Its simple working principle and easy installation make it an invaluable component for keeping circuits safe and providing effective current regulation.
