Through Hole Resistors are components used in a variety of applications that require the precise distribution of electrical current. The LR0204F18K is one such component, designed for specific applications and with a working principle based on the physics of electricity.

Application Field

The LR0204F18K is a resistor of the Through Hole category, also often referred to as “chassis-mount resistors.” This type of resistor is generally used in electronics and electrical applications which require a mechanical housing or enclosure. Examples of such applications include: fuse boxes, industrial control systems, and automotive wiring applications. In these cases, the size, shape, and structure of the LR0204F18K’s housing provides a sturdy platform to safely contain the electrical and mechanical connections.

Due to its wide operating temperature range and stable resistance over varying environmental parameters, the LR0204F18K is also often used in military and aerospace applications. The robust construction makes it resilient against extreme temperature fluctuations and pressure changes, as well as vibration and shock.

Overall, the LR0204F18K is most suitable for applications that require precision, durability, and reliable electrical current routing or insulation.

Working Principle

The LR0204F18K is an example of an ohmic resistor, whose resistance is a product of the amount of electrical current passing through it. This property, known as ohm’s law, states that the resistance is directly proportional to the voltage divided by the current. In other words, the greater the voltage, the greater the current. The LR0204F18K has a high tolerance (<0.5%), meaning that it can be relied upon to evenly divide the voltage in proportion to its resistance.

In the LR0204F18K, resistance is created by a coil of wire wrapped around a ceramic core, which is then covered in heat-resistant epoxy. This construction protects the wires from the elements while containing the electrical current. As current flows through the wire, a magnetic field is created, which helps dissipate energy and prevent the surplus buildup.

In addition to this, the LR0204F18K also features a temperature coefficient of resistance (TCR) to ensure stable performance in the event of temperature variances. A TCR is a measurement that measures the effect of temperature on resistance. Because of this feature, the LR0204F18K is especially well-suited for applications that require reliable current distribution over a broad temperature range.

Overall, the LR0204F18K is designed to ensure precise, consistent current division regardless of the environment or application. This makes it a highly sought-after resistor for a variety of industries.
