Through Hole Resistors refer to a type of electronics components that can restrict electrical current to a certain rate. The SQP500JB-390R is a part of this group and is designed for use in applications requiring high accuracy levels. In this article, we’ll take a look at the applications for this component and the internal workings to better understand how it functions.

The SQP500JB-390R is a bulk metal foil resistor that delivers superior low-temperature drift capabilities. With a thermal resistance of 0.093°C-in²/W, it’s an excellent choice for any application where temperature stability is key. This Through Hole Resistor is also designed with a high available resistance ohmic value range that starts at 3.90 Ω and goes up to 390 Ω. Its robust construction also allows it to be used in sections where temperature variation is minimal.

Aside from temperature variation, the SQP500JB-390R features excellent precision and accuracy. With a tolerance of 0.1%, its accuracy far outstrips other resistors of similar sizes. These capabilities make it a perfect choice for extremely precise uses like medical devices, aerospace, and instrumentation. Additionally, its capacitance-matched construction ensures a smooth, balanced sound maintain over a wide frequency spectrum.

The reasons behind the SQP500JB-390R’s superior performance lie in its intricate construction. To ensure absolute accuracy, the resistors are wound on high quality SRMG16 annealed copper foil. This foil is then subjected to a high-temperature etching process that further enhances its performance. The etching process creates a precisely formed component with an incredibly low ESR and minimal PCA. This ensures that accuracy levels are maintained even in heavily used and high shock environments.

Electrical stability is paramount when it comes to resistors and the SQP500JB-390R is no exception. The capacitor-matched winding process described above also offers superior mechanical and electrical stability. Additionally, the whole process is done in an inert environment which helps to protect it from contamination and damage. This, in turn, ensures that it can perform its duties reliably and for a much longer duration than other resistors.

In conclusion, the SQP500JB-390R Through Hole Resistor is an incredible component that has multiple dynamic application capabilities. From superior accuracy and precision to unbeatable electrical stability, this resistor is sure to become a go-to piece for any application requiring these capabilities. Furthermore, its construction methods and robust build ensure that it will last a long time and be extremely reliable over its life.
