Through hole resistors refer to resistors that are “through holes” or through-hole compatible in the sense that they can be “passed through” an isolated area or through a conductive material. Basically, through hole resistors are designed for use in applications where temperature and/or current external to the device will produce a large enough effect to alter the electrical characteristics of the resistor itself. This technology is quite common in military and aerospace applications due to its ability to withstand vibrations and electrical interference.One example of a through hole resistor is the MFR-25FTE52-39K resistor. This resistor is designed to be used in applications where frequency and temperature extremes are possible. This type of resistor is normally specified for rework applications, including military and aerospace designs.The MFR-25FTE52-39K is a surface-mount resistor that is able to maintain stable electrical characteristics over an extended temperature range of -55°C to +145°C. This type of resistor utilizes a low-resistance element that can provide maximum power dissipation of up to 1.2 watts in a 7mm x 5mm package. The resistor itself is made of high-temperature-resistant insulation such as alumina or glass epoxy and is designed to withstand the very high temperature of solder reflow and wave soldering. When it comes to the electrical characteristics of this particular resistor, it is rated to provide resistance values of 1KW – 2KW. This type of resistor is also available in higher-value (up to 200KW) and lower-value (down to 10 W) resistors. The tolerance and temperature stability of these resistors is also very good, with a tolerance of ±1% (+/-20ppm/°C maximum) and an operational temperature range of -55°C to +145°C.The MFR-25FTE52-39K resistor is also known as a metal film resistor. This type of resistor uses a metallized film deposited on the ceramic body to increase temperature stability and resistance accuracy. Since the metallized film increases the heat capacity of the resistor, this type of resistor is able to dissipate more power than other types of resistors. The working principle of the MFR-25FTE52-39K resistor is quite simple. It works on the principle that an electrical current will flow through a resistor when a voltage is applied across it. The resistance of the resistor will determine the amount of current that can flow through it. As the current flows, some of it is dissipated in the form of heat. The metallized film helps to disperse the heat away from the resistor body, allowing it to work within its specified temperature range.The MFR-25FTE52-39K resistor is commonly used in a variety of applications, ranging from high-power switching and measuring circuits to low-current precision circuits. It is widely used in automotive electronics, medical devices, industrial equipment, telecommunication systems, cellular phones, and other electronic components. Other applications for this type of resistor include discrete, it-sensing circuits, voltage references, and high-power motor control circuits.In conclusion, the MFR-25FTE52-39K resistor is a versatile and reliable resistor that offers excellent performance in applications where frequency and/or temperature extremes are possible. It is able to maintain its resistance value and stability over wide temperature ranges, while still providing good insulation and durability even in hostile environments. The MFR-25FTE52-39K resistor is a great choice for any project that requires stability, precision, and reliability.
