Through Hole Resistors are components that are used to control the flow of electrical current and to keep it limited by setting specific resistance values. In this context, the MFR25SFRE52-127K Through Hole Resistor plays an important role considering its operational features, like no-shell design and wide temperature rating. Its main application is for voltage divider and current limiter circuits.

The MFR25SFRE52-127K Through Hole Resistor is a non-inductive, high power, chip resistor. It features a 25-watt power dissipation, a ±1 percent temperature coefficient of resistance (TCR) and a temperature rating between -55°C (-67°F) and +155°C (311°F). The resistor has an operating voltage of 700 volts, a resistor value of 1000 ohms and a maximum over-current of 1250mA.

The terminals of the MFR25SFRE52-127K are wire-clad, enabling resistors to be placed in tight or non-standard applications with limited space. The terminals are also corrosion-resistant and solderable, making them ideal for soldering into densely populated circuit boards. Additionally, the non-shielded design of the MFR25SFRE52-127K prevents interference from being caused by the resistor when placed near other electronic components.

The working principle of the MFR25SFRE52-127K involves an electrical current entering the device and flowing through the resistor material. This resistance material is a semiconductor, typically an oxide, and the current flow is controlled by the voltage applied to the resistor. The amount of current that flows through the resistor is dependent on the amount of voltage applied, creating a consistent level of resistance. The presence of the resistor ensures that the current flow is kept within the established limits specified by the resistor. This is how the MFR25SFRE52-127K protects other components from voltage over-load or current surges.

The MFR25SFRE52-127K comprises a spiral of gold conductive strips, sand-blasted and bonded to the base material. This ensures a consistent electrical resistance, as the amount of material is carefully controlled during the production of the resistance material. The geometry of the spiral also provides reliability and stability, as the arrangement minimizes the amount of heat generated by the resistor while ensuring maximum power dissipation.

The MFR25SFRE52-127K Through Hole Resistor is mainly used in resistor-transistor logic (RTL) and logic circuit switching applications. It is also used in automotive circuits, integrated circuit (IC) development, and complex analogue circuitry. Its general applications range from temperature control and voltage regulator circuits, amplifier gain control, DC to DC converters, active filter circuits, automotive engine control circuits, and battery protection circuits.

The MFR25SFRE52-127K Through Hole Resistor is an invaluable tool for controlling current and setting voltage in electronic designs. Its features and versatile design make the resistor an effective and reliable presence in a wide variety of applications.
