Through Hole Resistors

Through hole resistors, also known as axial lead resistors, are typically used in circuits with high frequency and temperature applications, as well as providing superior electrical performance. The MFR-25FTE52-649K is a type of through-hole resistor designed to operate in these high-frequency and temperature environments. This resistor is designed to be mounted in a panel or chassis with nut and mounting hardware included.

MFR-25FTE52-649K Application Field

The MFR-25FTE52-649K through-hole resistor is a low-power, high-frequency device with a compact size and superior electrical properties. This device is ideal for use in automotive devices, such as throttles, speedometers, and power windows, as well as general-purpose applications. Furthermore, the MFR-25FTE52-649K is ideal for any application requiring low-power, high-frequency performance.

MFR-25FTE52-649K Working Principle

The MFR-25FTE52-649K operates on the principle of resistive materials. When current flows through conductors, electrons move to create electro-magnetic fields. The MFR-25FTE52-649K works by opposing the flow of electrons and creating opposing electromagnet fields. This opposition reduces the amplitude of the current traveling through the resistor and therefore reduces the amount of energy flowing through.The MFR-25FTE52-649K consists of two flat resistive plates with metalized contacts fixed to the sides. The metalized contacts contain a special type of alloy material which provides superior temperature and high-frequency stability. When current is applied to the contacts, the metalized contacts form a resistive barrier between the plates. This resistive barrier prevents the current from passing as desired, resulting in the desired level of resistance.

Conclusion

The MFR-25FTE52-649K through-hole resistor is a high-power, high-frequency device designed for use in automotive devices. It operates on the principle of resistive materials, where current is reduced through the use of metalized contacts which form a resistive barrier between two plates. This device is ideal for any application requiring superior temperature and frequency stability.
