Through Hole Resistors are perhaps the oldest form of resistors and have been around since the early 1800s. From the name, it is evident that these resistors are mounted through holes in the main body. They offer precision and accuracy when compared to other types of resistors, such as surface mount resistors. H4499RBZA resistors are the newest variant in the through-hole resistor family.

H4499RBZA is a high-performance thick-film resistor, consisting of several layers: an insulation layer, an active resistance layer, a top coat, and reinforced insulation layer. This structure provides the resistor with excellent stability and accuracy over a wide temperature range. The resistance of this resistor is determined by the ratio of the active resistive layer thickness and the insulation layer thickness. This design allows for tight resistance tolerances, usually only in the milliohm range.

H4499RBZA resistors find application in diverse industries such as automotive, electronics, communication and medical sectors. In the automotive industry, these resistors are used for power management solutions, particularly for application requiring precision control of voltage and current. The resistors are also used in low and medium power applications such as LED lighting. In the electronic industry, they are used in precision sensors, analog circuitry, and in motor control. Due to their high tolerance, these resistors are ideal for these applications.

In the communication industry, these resistors are used in cellular base stations, wireless communication systems, and mobile handsets. They provide high process reliability and precision, as required in these applications. In the medical industry, they are used for blood pressure and other medical grade measurements, since precision control is an absolute must in these applications. In general, these resistors are used in any application where tight tolerance and excellent accuracy is needed.

The working principle of the H4499RBZA resistor is simple. The resistor comprises of two layers, the insulation layer and the active resistive layer. When electricity passes through these layers, a resistive force is created, which is proportional to the amount of electricity passing through it. This resistive force impedes the flow of electricity and lowers the voltage and current passing through the resistor. The resistance of the resistor is determined by the ratio of the two layers, and the amount of current passing through it. This working principle is key to its application in various industries.

H4499RBZA resistors offer excellent accuracy and reliability to a variety of application areas. The resistor is highly stable and offers tight tolerance, which makes it ideal for applications requiring precision control. The working principle of the resistor is based on simple physics and is easy to understand. This wide array of features make it a viable option for any project requiring accurate and reliable control of electricity.
