Through Hole Resistors: MG14JT750K application field and working principle

Through hole resistors are resistors that are generally used when surface mounted components fail to provide adequate heat dissipation or have high power ratings. Through hole resistors are commonly used in applications from consumer electronics to precision industrial and medical equipment. The MG14JT750K is a type of through-hole resistors which has low cost and excellent performance features.

Application Field of MG14JT750K

The MG14JT750K is a metal-glazed resistor with a power rating of 750 mW. It is ideal for applications that require high accuracy and repeatability, such as precision metering and signal conditioning equipment. It is also suitable for harsh environment applications such as automotive electronics, and for frequency sensitive applications such as filters and loudspeaker crossovers. The resistance value range for the MG14JT750K is from 10 ohm to 1Mohm. The allowable overpower is 5 times the power rating for an ambient temperature of 23°C.

Working Principle of MG14JT750K

The MG14JT750K is a resistor with a metal-glazed (MG) resistance element. The resistance element is made of a thin film of metal deposited on a ceramic substrate. The metal is formed into a spiral pattern with a specific number of turns and a specific number of spaces between the turns.When a current passes through the resistor, the resistance of the resistor is determined by the length of the thin metal spiral as well as the material of the metal. The material of the metal is chosen carefully to ensure that the resistance value is precise and does not drift with changing temperature. Temperature changes cause expansion and contraction of the metal spiral, which alters its resistance. The substrate material is engineered to minimize such changes in resistance due to temperature.

Conclusion

The MG14JT750K is a low cost, high precision through hole resistor ideal for applications such as automotive electronics, precision metering, and signal conditioning equipment. It features the metal-glazed resistance element, with metal chosen carefully to provide a precise and stable value range. The resistor has a power rating of 750 mW and an allowable over power rating of 5 times the power rating for an ambient temperature of 23°C. Overall, the MG14JT750K is a reliable resistor suitable for a wide range of applications. It is a valuable component for circuit boards and other electrical systems where reliable and precise resistor values are required.
