Through hole resistors are essential components of most circuitry, enabling electrical current to be regulated and distributed as desired. Among the most widely used through hole resistors is RC14KB330R—a low-noise resistor that offers superior stability and temperature characteristics. This guide explains the principles of through hole resistor design and looks at the specific application field and working principle of RC14KB330R resistors.

Overview of Through Hole Resistor Design

Through hole resistors are typically constructed using one of two construction techniques. Either a single-sided or double-sided resistor construction is applied. With a single-sided resistor, the resistor element consists of a single metal track which is isolated from the substrate. This track is resistant to voltage and current, limiting the flow of electricity through the resistor and thereby influencing the current and voltage values.

With double-sided resistor construction, a second metal track is placed on the opposite side of the substrate. These two tracks are connected with a continuous layer of insulation between them and are connected to parallel contact pads. This construction enables the resistor to be used in many types of circuits without additional handling and supports a wide range of voltage and current ratings. It has the advantage of a larger form factor and allows for a greater range of resistance values.

Application Field and Working Principle of RC14KB330R Resistor

The RC14KB330R resistor is designed for use in low-noise applications and offers excellent stability and high temperature performance. It is a through hole, double-sided resistor with the following characteristics:

• Power rating: 330mW
• Resistance range: 0.1 ohms to 1 meg ohms
• Temperature range: -55C to +125C
• Stability: 5ppm/°C
• Noise level: Less than 10nV/Hz

The RC14KB330R is ideally suited for use in battery-operated devices, such as cell phones and portable audio players, as well as for use in high-temperature environments, such as in automotive or industrial applications. It is also well-suited for use in precision measuring instruments, test equipment, and medical devices.

The working principle of the RC14KB330R is relatively simple. The resistor’s parallel contact pads form the two points at which the resistance is altered. When electrical current flows into one of the contact pads, it flows through the resistor element and is divided into two streams. One stream travels through the resistor’s metal track and the other travels through the insulation between the tracks. The voltage at the other contact pad is equal to the voltage of the resistor element, minus the voltage drop caused by the electrical current flowing through the resistor.

The resistance value of the RC14KB330R is determined by the diameter of the metal tracks, the length of the insulation between the tracks, and the material of the metal track. For example, a resistor with larger diameter tracks will have a greater resistance value than one with smaller diameter tracks, and a resistor with more insulation will have a greater resistance value than one with less insulation. The material of the metal track itself—e.g., copper, alloy, or carbon—can also influence the resistance value.

Lastly, the working principle of the RC14KB330R also relies on its low-noise characteristics. The resistor is designed to have a low-noise profile, meaning it is able to reduce thermal noise and parastic noise caused by the resistor’s inductive/capacitive components. This helps ensure that signal integrity is maintained in high-performance systems.

Conclusion

The RC14KB330R is an excellent choice for low-noise applications requiring superior stability and temperature characteristics. Its through hole construction makes it easy to use in many types of circuitry and it has a wide range of resistance values, from 0.1 ohms to 1 meg ohms. The working principle of the RC14KB330R depends on its two contact pads and the metal track between them, as well as its low-noise characteristics, which ensures signal integrity in high-performance systems. Overall, the RC14KB330R is an ideal through hole resistor for applications such as battery-operated devices, high-temperature environments, and precision measuring instruments.
