Through Hole Resistors are ubiquitous in electronics, from complex circuits designs to simple hobby projects. One of the most common and versatile of these resistors is the B12J800E design. While this design is by no means “state of the art” technology, it does provide stable performance over a wide range of applications. It is a robust and reliable design, and its reasonable cost makes it ideal for hobbyists, prototypers, and in a wide variety of commercial projects.

The B12J800E is a 12.6mm x 8.0mm x 1.5mm through hole resistor, based on an “axial lead” design. The leads of the resistor are composed of a metal that has been coated or plated with a conductive material. The resistor itself is a ceramic-filled material that contains a multitude of granules containing carbon or other conductive material. The leads are soldered onto the PCB, with the ceramic of the resistor buried between the traces on the board.

The B12J800E is designed to have a resistance of 800Ω, although this value can vary based on the tolerance. The tolerance of the resistor indicates how close the actual value of the resistance is to the stated value on the resistor. Common tolerance values for the B12J800E are 1%, 5%, and 10%. While these are the most common, resistors with different tolerances are available.

The B12J800E is used in a wide variety of applications, from hobbyist projects such as Arduino and Raspberry Pi to commercial projects such as electronic control systems and industrial automation controllers. The resistor can be used for voltage regulation in power supplies, such as restricting the voltage to a certain value, or as a current limiting device.

In addition, the resistor can be used in both AC and DC circuits, making it very versatile. It is particularly useful in RF circuits, as it can help to reduce the amount of radio frequency interference generated by the circuit. The resistor is also used in some automotive applications, including fuel injectors and ignition systems.

The B12J800E is well equipped to handle most applications it might be used for, as its overall power rating is 1/4W. This is enough to handle most circuits, but it’s important to keep in mind that the power rating may need to be increased for more complex circuits. Additionally, it should be noted that the resistor dissipates heat while in use, so it is important to consider adequate ventilation during design.

In terms of working principle, the B12J800E follows Ohm’s law, which states that the voltage drop across the resistor is equal to the product of the current passing through it and the resistance of the resistor. In other words, the voltage is proportional to the amount of current passing through the resistor, and it is inversely proportional to the resistance of the resistor. This relationship allows the voltage to be regulated and controlled by adjusting the resistance of the resistor.

The B12J800E is a versatile and reliable through hole resistor, and its reasonable cost makes it an ideal choice for a variety of projects. It can be used in a wide range of applications, including voltage regulation, current limiting, and RF reduction. It is easy to work with, thanks to its axial lead design, and its power rating is 1/4W, making it suitable for most applications. Additionally, it follows Ohm’s law, allowing for precise control over voltage.
