Through hole resistors are a type of resistor that are commonly used in electronics and electrical engineering as a form of protection against a variety of electrical conditions. The OM9115E-R58 is an example of one such resistors that is specifically designed for high power applications and offers superior performance compared to other through hole resistors. This article will discuss the application field and working principle of the OM9115E-R58 in order to better understand its capabilities.

The OM9115E-R58 is a high-performance, through hole power resistor designed for current/voltage limiting applications, primarily in automotive and industrial applications. It is composed of a high-temperature ceramic core surrounded by an aluminum housing. This combination of materials allows for high power dissipation in a small package size, making it an ideal choice for high-density applications such as power supplies and automotive control units. The resistor is also capable of withstanding high temperatures, making it suitable for harsh environmental conditions.

The OM9115E-R58 is designed for use in a current limiting circuit, where it acts as a current-limiting device. It is typically connected in series with the load to be protected and is wired to a voltage source. When the voltage across the resistor exceeds a certain level, the resistor begins to dissipate some of the current, effectively limiting the current that reaches the load. This type of current limiting can help protect sensitive components from damage due to excessive current.

The OM9115E-R58 is also able to sense when the voltage drops below a certain threshold, at which point it will conduct current in the opposite direction. This is called the reverse bias protection feature, and it helps to protect the protected component from sudden voltage surges. In this way, the OM9115E-R58 acts as a protection shield for the component, ensuring that the protected component is not damaged by large currents or voltage surges.

In addition to its current limiting capabilities, the OM9115E-R58 is also capable of providing helpful feedback on current and voltage levels in the circuit. This is especially useful for circuit designs that require precise current/voltage thresholds. The resistor can provide feedback regarding voltage levels, so that the circuit can be adjusted accordingly if the power levels are too high or too low.

The OM9115E-R58 is also designed to withstand extreme temperatures. It has a minimum temperature rating of -40°C and can safely handle temperatures as high as +125°C. This ensures that the resistor will be able to safely handle extreme environmental conditions without any damage or loss of its performance.

Overall, the OM9115E-R58 is an excellent choice for high power applications due to its superior performance and reliable protection features. It is designed for current/voltage limiting circuits, and is able to provide useful feedback on current/voltage levels in the circuit. The resistor is also able to withstand extreme temperatures, making it suitable for harsh environmental conditions. All of these features make the OM9115E-R58 an ideal choice for through hole resistors, making it an invaluable tool in any circuit design.
