Through Hole Resistors

A through hole resistor (THR) is a type of resistor that is used in circuits in which the current is not strong enough to require a large heatsink. The resistor is constructed with an external lead wire which passes through the resistor body and into the circuit board as opposed to surface mount resistors which are attached to one side of the circuit board. The resistor is also constructed with a metalized film that is wrapped around the cylindrical body, providing the resistance necessary for the device to function. The lead wire and the metalized film combine to form a single unit, allowing the resistor to be placed into a suitable design cavity within the circuit board.

THRs are commonly used in many electronic circuits, such as in power supplies, audio/video applications, and industrial equipment. In these applications, the THR is used to reduce the voltage or current on the circuit and prevent damage to other components. For example, in power supplies, a THR can be used to regulate the current to the output. Additionally, they are used in motor control applications, such as a washing machine or a dishwasher, to regulate the current within the motor. In audio/video applications, the THR is used to eliminate interference between the circuits by providing a predictable amount of resistance.

In addition to the common applications listed above, THR resistors can be used in a variety of specialized equipment. For example, the RNC55H8982BSR36 is a through hole resistor that is specially designed for use in lighting control systems. This type of THR resistor is optimized for use in circuits that are exposed to high temperatures and vibration, such as LED lighting control systems, automotive and industrial lighting systems, and audio/video systems.

The RNC56H8982BSR36 THR resistor features a unique design that makes it ideal for use in specialized applications. The resistor is constructed with a high-purity metalized charcoal film that is wrapped around the cylindrical body, providing the necessary amount of resistance and stability. The resistor also features a molded metal sleeve that connects the lead wires to the resistor body, creating a strong and stable connection between the resistor and the circuit board. Additionally, the molded metal sleeve is designed to reduce electrical noise and prevent EMI/RFI interference.

When it comes to working principle, THR resistors operate on the same basic principle as other types of resistors. This type of resistor is constructed so that the current passing through it is reduced, reducing the power dissipated in the circuit. This is accomplished by creating a voltage drop across the resistor by effectively limiting the current that can pass through it. The current must travel along the entire length of the resistor before exiting the circuit. This action creates a greater resistance and thus, a greater voltage drop.

In conclusion, THR resistors are a popular type of resistor used in a variety of applications. The RNC55H8982BSR36 THR resistor, in particular, is specially designed for use in lighting control systems. This THR has been optimized for use in circuits that are exposed to high temperatures and vibration. The resistor features a high-purity metalized charcoal film wrapped around the cylindrical body, and a molded metal sleeve that connects the two lead wires to the resistor body. When it comes to working principle, THR resistors operate on the same basic principle as other types of resistors: reducing the power dissipated in the circuit by creating a voltage drop across the resistor.
