Introduction
Through Hole Resistors, or THRs, are an electrical component used to regulate the amount of current that passes through an electrical circuit. They are the most common type of resistor available in the market today and are used in a wide variety of applications, including consumer electronics, industrial machinery, and aerospace applications.21J10RE application field and working principle
The 21J10RE THR is a high-performance THR that is designed for use in high-frequency, high-reliability circuits, such as those found in military and aerospace applications. It is a wirewound resistor that is physically larger than traditional THRs and is designed to dissipate more heat in order to handle higher power levels. It is also designed for increased accuracy and stability over a wide temperature range.The 21J10RE is designed with a glass-coated steel core, a special wirewound resistor element, and an epoxy-sealed construction for added protection against harsh environmental conditions, such as humidity, temperature extremes, and vibration. The resistor element in the THR consists of a low resistance wirewound around the core and a coiled wire around the outer layer for insulation. The resistance of the THR is determined by the number of windings around the core and the thickness of the wound wire.The 21J10RE THR operates by acting as a “load” on the circuit, limiting the amount of current that passes through. When a current is applied to the circuit, the current is limited by the resistance of the THR and the resulting voltage drop across the THR. This voltage drop is what results in the desired current limitation. The current limitation of the THR can be adjusted by changing the number of windings around the core or the thickness of the wire used.The 21J10RE THR is well-suited for applications requiring high power handling and stability over a wide temperature range. It is also highly reliable, durable, and lightweight, making it ideal for use in airborne and military applications. The THR also meets MIL-SPEC standards for shock, vibration, humidity, and temperature variation.Conclusion
The 21J10RE THR is a highly versatile THR designed for use in high-performance and high-reliability circuits. Its high power handling capacity, stability over a wide temperature range, and MIL-SPEC compliance make it an ideal choice for a wide range of applications, including consumer electronics, industrial machinery, and aerospace applications.
