Through Hole Resistors, such as the FMF-25FTF52-24K, are one of the most common fixes in the electronics industry for controlling current and voltage levels in circuits. The FMF-25FTF52-24K is a special type of resistor, given its thickness restricts it to being used only in through hole applications. This article will discuss the application fields and working principle of the FMF-25FTF52-24K special resistor.

The first step in understanding the FMF-25FTF52-24K is to consider its application in circuits. It is designed for use in either digital or analog circuits, and is most appropriate for local bypass for feedback resistors in high-speed switch-mode power supplies (SMPS) power supply solutions. It is made with a ceramic body and two embedded silver electrodes on each side, and is ideal for high current and high voltage applications in power units and other circuit designs.

Because of its thickness, the FMF-25FTF52-24K through hole resistor is a specialized type of resistor. It features a power rating of 1W and resistance value from 10 ohms – 1M ohms, with a voltage rating of up to 350V AC/DC. It is built with a Teflon body and solderable/potting coatings, making it is highly reliable in high-temperature applications. The body also features an anti-acling design to ensure reliable mounting.

To understand the working principle of the FMF-25FTF52-24K, it is important to know that it is generally used for voltage or current stabilization in power supplies. Its internal structure consists of two silver electrodes, one flat on the top and one apron on the bottom, that span the resistor body across its entire width. The two electrodes are spaced apart and shorted together with an indium-tin alloy, which has very low resistance and is highly resistant to corrosion. This alloy layer is in direct contact with the silver electrodes allowing a low resistance current to flow across the entire resistor body.

The indium-tin alloy layer is insulated by a layer of low-K dielectric material, such as silicon oxide, which prevents shorting and helps maintain constant voltage throughout the resistor body. To complete the circuit, the silver electrodes and alloy layer are connected to two external terminals, which can easily be soldered onto the PCB.

The FMF-25FTF52-24K through hole resistor offers several advantages when used in power supply applications. Its low-K dielectric layer ensures constant voltage regardless of changes in temperature or environmental conditions, while its low resistance allows for high currents without overheating the resistor body. Additionally, the indium-tin alloy connection ensures low series resistance and reduces magnetic fields, which is essential in high-speed applications. Furthermore, its anti-acling design helps to secure the resistor body to the PCB even in harsh environments.

In summary, the FMF-25FTF52-24K through hole resistor combines a thick ceramic body, two silver electrodes, and an indium-tin alloy to provide a reliable and powerful solution for voltage and current stabilization in power units and other circuit designs. Its low-K dielectric layer not only ensures constant voltage, but also reduces magnetic fields, while its anti-acling design ensures reliable mounting in harsh environments. With these features combined, the FMF-25FTF52-24K is a versatile and highly reliable resistive component for a wide range of application fields.
