Through Hole Resistors, such as the RNC55J4932BSRSL, are discrete components that oppose the flow of current. They are used to limit the current in circuits, maintain a voltage level, absorb spikes or surges in circuits, and provide or alter specific impedance levels to the voltage or current signals. The Through Hole Resistors designation for RNC55J4932BSRSL consists of three parts. The RNC55J is the manufacturer’s part number, 4932 is the actual resistance value, and BSRSL is the tolerance. The tolerance will indicate how accurate the resistor\'s true resistance value will come close to the indicated value.

In addition to the designator RNC55J4932BSRSL, Through Hole Resistors will have additional printed markings typically located near the body of the resistor. It will provide additional information, such as wattage rating, failure rate (F.R.), and voltage derating. However, it is important to note that there may not be any printed markings at all. Some engineers prefer to make deductions from the resistors’ physical shape, size, and color band characteristics instead.

The working principle of Through Hole Resistors, such as the RNC55J4932BSRSL, is straightforward. The physical shape and number of bands of the resistor will correspond to the resistor’s manufacturer’s part number. Through Hole Resistors offer the best performance capabilities because they can use longer passes and larger land sizes. As a result, they generally have the highest power rating and stability.

When electrical energy is applied to a Through Hole Resistor, such as the RNC55J4932BSRSL, the current runs through it, generating voltage. The voltage is divided into two components; one is the “applied” voltage, and the other is the “drop” voltage, which is the voltage that is developed across the resistor due to the current running through it. Through Hole Resistors are designed in such a way that they can withstand high levels of voltage and power. Some Through Hole Resistors are also designed to adjust the magnitude of current passing through a circuit by using its resistance. This method of regulating current flow is calledvariable resistors.

The RNC55J4932BSRSL is a general purpose Through Hole Resistor used in many applications requiring reliable and accurate value. These applications include power supply, linear regulated supply, or audio amplifier circuits, motor control, or discrete LED lighting. This type of resistor is also used in circuits as shield against dangerous voltage or surplus current surges. In many cases, multiple resistors may be connected in parallel or in series to change its resistance or power rating.

Through Hole Resistors, such as the RNC55J4932BSRSL, offer reliable performance, accurate value, and excellent stability and power ratings. They offer the advantage of being large, allowing them to be mounted and soldered easily. They are typically used in higher voltage power applications because they allow more power to pass safely through a circuit due to their thermal characteristics. Despite these advantages, the resistance values cannot be adjusted for applications that require precise control of current or voltage.
