H4187KDYA Working Principle

The H4187KDYA Resistance is a resistor with a constant resistance value throughout its life and an internal temperature coefficient of resistance. It is composed of a Carbon Film resistance element, lead wires, and a case. The resistance element is composed of tantalum (Ta) and zinc (Zn) oxides which are applied to a non-conductive substrate and then fused together with a high-temperature process. The process results in an incredibly stable perimetric design and variable parameters for dynamic tuning operation.

The resistance element is connected to a substrate material, which is then connected to two wires, providing a closed loop for current flow. As current flows through the resistor, a voltage drop occurs which is proportional to the resistance value and current. This voltage drop is detected by the appropriate meter and converted into a signal “measuring” the current.

The H4187KDYA Resistor also has a temperature coefficient of resistance, which is the ratio of change in resistance as the temperature changes. This is an important parameter for accurate testing in a wide range of operational temperatures, from -55° C to +125° C.

In addition, the H4187KDYA offers an impressive level of thermal shock protection, meaning it can withstand frequent temperature fluctuations. This allows it to be used in environments where temperature fluctuations can erase or reduce the resistance value of a conventional resistor.

The H4187KDYA is also an extremely reliable component, with a lifetime of up to 10 million operations. Furthermore, its thermally stable design ensures that its resistance values are maintained throughout its life.

Conclusion

The H4187KDYA Through-Hole Resistor is an accurate, reliable, and thermally stable component ideal for all your voltage and current control requirements. Its unique design and wide range of features and benefits make it a popular choice for a variety of applications, from automotive batteries to circuit board manufacturing and testing.
