Through Hole Resistors: H816R9BZA application field and working principle

Through Hole resistors are one of the most frequently used type of resistors because they are cost-effective and durable, making them ideal for a variety of different applications. The H816R9BZA is a particular type of through hole resistor that features a convex resistive element, which provides superior rated operation, compared to its flat resistive element counterparts. With this type of resistor, users can expect a higher level of accuracy, as well as improved performance under extreme environmental conditions.

When discussing the applications of the H816R9BZA resistor, it is important to note that this specifically designed component is best used in industrial, military, and aerospace applications. Generally speaking, these components are designed to handle higher power densities across a wider temperature range than traditional through-hole resistors. The nominal rated maximum power of the H816R9BZA is 50w at 25°C, which is significantly higher than other standard resistors.

In terms of working principle, the H816R9BZA is a typical four-terminal resistor, with a convex resistive element in the center, and two resistive elements forming the terminals. The resistive element is typically formed from a thin metal oxide layer, such as aluminum, tantalum, or other materials. This resistive layer is then coated with a silicone gel or other protective layer. This helps to protect the metal oxide layer from sudden temperature or stress-induced changes, as well as providing insulation.

To operate, electrical current is passed through the resistive element of a H816R9BZA resistor. The current is said to divide equally between the two resistive elements and the impedance of the device is proportional to the ratio of the current flowing through each element. As it is a through hole resistor, it is also important to note that the current is limited at two points, namely the two terminals. At these terminals, the current is restricted in order to prevent any damage to the device.

When it comes to the temperature rating of a H816R9BZA, it is essential to keep in mind that the Celsius rating is taken at the recommended rated maximum power level. This helps to ensure that the resistor is able to operate at its specified temperature level without any problems. With regards to the ceiling temperature of the part, this is set by the rated maximum power and should not exceed this level in order to prevent any damage.

In conclusion, the H816R9BZA is a reliable and cost-effective through hole resistor that is specifically designed for industrial, military, and aerospace applications. This resistor features a convex resistive element, which provides superior rated operation and performance when compared to its flat resistive element counterparts. When using this resistor, it is essential that the rated maximum power level should not be exceeded in order to prevent any damage.
