It is primarily used in aerospace, automotive and defense applications requiring in-circuit stability and increased resistance temperatures. The device has a rated power of 2 Watts and is available in a range of available resistances from 5ohms to 25kohms. The through-hole design of MFR25SFTF52-2K offers precise resistance values and autosealing technology to ensure superior electrical connection properties in demanding environmental applications. The autosealing process prevents electrical contact between the leads during demanding environmental conditions. The device is designed to meet the requirements of harsh working conditions such as high temperature, high humidity, vibrations, shocks, corrosive chemicals and other extreme environmental circumstances. The electronic component is also engineered to provide superior electrical contact in high energy applications and long-term operation at high temperatures and under extreme pressure. The MFR25SFTF52-2K comprises of a ceramic heat sink, copper-plated lead frames, low-temperature-resistant gold-plated contacts and a specific resistive element made from Nichrome alloy. The combination of these materials ensures low resistance to current, high temperature resistance, stability and precision. The working principle of the MFR25SFTF52-2K lies in the Nichrome element. Nichrome, a combination of nickel and chromium, has a higher resistance to current and, therefore, creates a resistance heater when an electrical current flows through it. This resistance of the Nichrome element generates heat and, at the same time, decreases the current flowing through the component. This, in turn, leads to a steady voltage across the resistor. The resistor dissipates part of the energy in the form of heat. The application of MFR25SFTF52-2K components includes remote sensing applications, switching applications, voltage buffering, plus relative and absolute sensors. The device is also found in measuring and testing applications, as well as in other industries that require dependable electrical parameters at the highest level of accuracy. The MFR25SFTF52-2K features a wide range of operational temperature ranges from -55°C to +125°C, low noise level and long-term stability. Its high power rating and just 0.025W of maximum power dissipation, along with its excellent signal-to-noise ratio provides superior reliability and dependability for critical applications such as aerospace, automotive and defense applications. Overall, the MFR25SFTF52-2K is a high-accuracy and reliable through-hole resistor, which provides excellent mechanical robustness, electrical contact properties, stability and quality. With its wide range of available resistances and excellent operational temperature range, it is the perfect solution for aerospace, automotive and defense applications.
