Through Hole Resistors

Through hole resistors, also known as through-hole packages, are commonly used components in electronic circuits and systems, featuring a type of physically and electrically stable and efficient construction. These devices are typically placed on printed circuit boards (PCBs) and have a hole that runs through the center of them, allowing for easy mounting and electrical connection. The size of the hole corresponds to the size of the component, making it easy to identify and place the component correctly.The MFR25SDRF52-681R is an example of a through hole resistor, which is a component used to create electrical resistance in a circuit. Commonly referred to as “fixed resistors”, through hole resistors come in a variety of shapes such as cylinders or rectangles and may feature a few different characteristics. One of the most common characteristics of through hole resistors is their resistance value, which is measured in ohms, along with their tolerance rating, which states how accurate the resistor is. Other key characteristics of through hole resistors include their power rating, which indicates how much power they can handle, and their temperature coefficient, which indicates how much the resistance value changes with temperature.In general, the MFR25SDRF52-681R resistor is a low power resistor, typically used in applications that require high accuracy or precision. It has a resistance value of 681 ohms, along with a tolerance rating of ±5%, indicating that its accuracy is quite high. The power rating of the MFR25SDRF52-681R is 0.1 watts and its temperature coefficient is Zero. With its properties and attributes, the MFR25SDRF52-681R is ideally suited for a variety of circuits and applications such as voltage dividers, timing circuits, frequency control, voltage regulation and signal filtering.Due to its accurate and stable properties, the through hole resistor is often used in Microprocessors, Analog/Digital signals and AC/DC converters where accuracy is essential and any wrong calculation can cause the system to be shut down. Through hole resistors can also be found in the automotive industry, where they are useful in controlling electric motors, airbags and fuel injection systems. These resistors are also found in various types of Medical and Industrial equipment, where they can be used as temperature sensing and current limiting devices.In terms of working principle, through hole resistors are designed to convert electrical energy into heat energy, which is the basis of their operation. Essentially, they act like a switch, allowing current to travel through them when open and keeping the current restricted when closed. The electrical resistance of the through hole resistor is created by the doping of impurities to the resistor\'s core material, typically a ceramic or metal material. The impurities create a barrier that restricts the flow of current, resulting in a drop in voltage. This drop in voltage is determined by the size and shape of the resistor itself, as well as the type and amount of doping possessing the material.Overall, the MFR25SDRF52-681R is an important component, that is commonly utilised in electronic circuit designs. Its unique construction, characterized by a hole running through the middle, provides for a physically and electrically stable and efficient design. With its resistance value of 681 ohms, a tolerance rating of ±5% and a power rating 0.1 watts, the MFR25SDRF52-681R is ideally suited for a variety of circuit and application where accuracy and precision is key. Due to its properties, the through hole resistor is commonly found in a variety of industries, such as automotive and medical, and is essential for providing electronic circuit protection.
