Through Hole Resistors

Through hole resistors are commonly used within the scope of electrical engineering and have been around for many decades. Despite the vast improvements and advancements of surface mount or SMT resistors, the design of the through hole resistor is still commonly seen, especially in older and less reliable applications. The LLC450JB-0R051 is one such through hole resistor with a particular field of application and working principle.

Application Field of LLC450JB-0R051

The LLC450JB-0R051 was designed to work in the range of power electronics which require precise control of electrical resistance. As power electronics such as inverters, controllers and motor drives increase their complexity and voltage range, the need for more accurately controlled resistors arises. The LLC450JB-0R051 is ideal for these types of power electronics applications as it has a wide temperature range of -55 to +155 C and a temperature coefficient of -30 to +60 ppm. Additionally, its flame retardant properties also make it ideal for use in high-voltage applications.

Working Principle of LLC450JB-0R051

The LLC450JB-0R051 works on the principle of utilizing low-resistance wires arranged together in a grid pattern. This wire grid design serves to provide more accurate resistive control and is much more reliable than a standard resistor. The wires within the LLC450JB-0R051 are arranged to give an accurate resistance which changes only slightly with respect to temperature and voltage. The LLC450JB-0R051 can also serve to dissipate heat as well due to its low resistance grid design.

Furthermore, the LLC450JB-0R051 also utilizes a constrained-mount design, meaning that it is much better at tolerating vibration. This vibration tolerance is achieved by its mounting plate which holds the resistor securely and absorbs any shocks to the resistor. The exclusive constrained-mount design of the LLC450JB-0R051 also allows it to be used in applications in which a normal resistor is too delicate, such as in aviation and marine applications.

Overall, the LLC450JB-0R051 is a very robust through hole resistor with impressive temperature and vibration tolerance properties as well as being accuracy in maintaining resistance. This makes it an ideal choice for applications that require precise control of resistance and require better electrical and thermal performance than the standard resistor.
