Through Hole Resistors

Resistors in throughhole form are one of the oldest forms of resistors available. Invented in 1953, throughhole resistors are one of the most common forms of resistors used in the world today.Throughhole resistors are designed to mount on the surface of a printed circuit board (PCB). The two leads of the resistor go through the holes of PCBs and solder to a pair of copper pads on the bottom side of the board. Because of this, they have become known as "throughhole resistors".The MFR25SFTF52-226K is a throughhole resistor specifically designed for use with printed circuit boards. This type of resistor contains a metal-oxide-film resistor core, which is encased within a rectangular case. The two leads of the resistor extend from either side of the rectangle, each containing a small copper pad at the end of the lead. This type of resistor is known for having a superior power rating, and its large case measures 25mm x 15mm x 12mm (or 1 in. x 0.59 in. x 0.47 in.).As with most throughhole resistors, the MFR25SFTF52-226K was designed to be used in the following applications: audio amplifiers, power supplies, radio frequency (RF) circuits, and power circuits. In particular, this type of resistor is often used in big industrial applications, as it is able to handle high levels of power.In terms of its working principle, the MFR25SFTF52-226K operates in the same way as any other throughhole resistor. That is, it limits the flow of electricity through a circuit, while also performing the role of a voltage divider. In other words, it is designed to reduce and control the current in the circuit, allowing for precise control over the electronic devices in the system. When it comes to the specific characteristics of the MFR25SFTF52-226K, it is rated at a maximum power of 5 Watts. Its resistance range is from 85 to 900 ohms, and a tolerance of ±10%. Its temperature coefficient is equal to 100ppm/°C, and it has a dielectric strength of 2KV ≈ 1minute. Lastly, it has an insulation resistance of 500MΩ min.Throughhole resistors have become an essential component in many electrical systems. The MFR25SFTF52-226K specifically has been designed to provide reliable operation in a wide range of applications, from industrial systems to audio amplifiers. Its superior power rating coupled with its small size make this an ideal choice for a wide range of uses.
