Through Hole Resistors - FMF-25FRF52-1K

Through hole resistors refer to the most common form of resistor termed axial leaded resistors. These resistors are typically much larger than the surface mount varieties as they have two metal leads that run through the components body, exiting it at each end. In the case of the FMF-25FRF52-1K, these leads measure 0.25-inches in length.

For the FMF-25FRF52-1K, it is a 1-kilohm fixed resistor, and nominal power is 1/4 watt. Its resistance tolerance is ±1%, and temperature coefficient is ±100 ppm/C. The resistance temperature coefficient (TCR) of this unit is a maximum of 2 ppm/C meaning that it will minorly change its electrical resistance with a change in temperature.

Application Field

As through hole resistors, this type of resistor is mostly used in applications where size or weight constraints are not an issue. The FMF-25FRF52-1K is often used in industrial and consumer electronics, testing, and measuring applications, and is most widely applied in the industrial sector. A common usage of these resistors in the industrial sector is to act as current or voltage limiting resistors, where they can be used to dampen or stop overloading, protect sensitive components from damage, and filter out any interfering signals.

Working Principle

The FMF-25FRF52-1K works on the principle of the electrochemical reaction of a conductor material in an electrolyte solution. When a current flows through the electrolyte, it creates a potential difference, and the current passes through the terminal wires and the resistor body. The resistor material itself is typically made of a carbon or metal oxide mixture, and the material’s properties determine the resulting resistance across the body. As the current passes through the resistor, it will experience a drop across the terminals due to the resistors resistance value.

The resistor is constructed in such a way that the resistors resistance does not dramatically increase or decrease with temperature changes, meaning it will generally stay consistent over time making it an ideal choice for many industrial applications. The device is also encased in a heat resistant casing to protect the device from high temperatures and any oncoming electrical shock.

Conclusion

The FMF-25FRF52-1K through hole resistor is a reliable and durable solution for many engineering applications, as its size and tolerance remain consistent over time and temperature levels. With electrical current limits and heat protection, this type of resistor is an ideal choice for industrial applications, where it can be used to protect, dampen, or filter out electrical interference between components.
