Through Hole Resistors

RC12JT3R90 is a type of through hole resistor that can be used in a variety of applications, including personal computers, automotive, and medical electronics. The RC12JT3R90 is a low-cost alternative to through-hole resistors with a higher dissipation rating.

Application Field

In the electronics industry, RC12JT3R90 are commonly used to reduce current intensity or voltage intensity before they reach any device. In this way, they protect the downstream device from overvoltage or excessive electrical surges.

They are often used in power supplies, providing short circuit protection, and can be found in a variety of devices, such as industrial power supplies, automotive electronic control units, medical devices, and personal computers.

Working Principle

Essentially, RC12JT3R90 are resistors that limit the flow of electric current. They contain an external resistor that impedes electric current flow from the connecting wire all the way to the logic portion of the device . They are typically composed of a ceramic or metal outer casing housing the resistor, terminals for connecting to power and more components. It is the resistor itself that limits the flow of electrical current.

With through-hole resistors, when the external resistor heats up during operation, the ceramic casing surrounding it will also heat up. This increases the thermal resistance between the resistor and the other connected components, meaning the device can effectively limit the amount of current passing through it. This is the primary use of a through-hole resistor.

In addition, through-hole resistors are usually highly reliable due to their ceramic or metal casing, which provides extra protection from electrical shocks and other contaminants. This makes them a great choice for use in environments that may be prone to interference and power issues.

Finally, through-hole resistors often have a much longer shelf life than their surface mount counterparts due to their robust construction. This makes them suitable for long-term projects or environments where high reliability is expected.

Overall, RC12JT3R90 through-hole resistors are an economical and reliable option for a variety of applications. They are easy to install, can handle a range of current variations, and last long enough for almost any application.
