A through hole resistor is a variety of resistor used in both through-hole and surface-mount designs and applications. This type of resistor is so named because it has two metal pins or leads that are inserted into two round holes in a circuit board. The resistors have a heat-resistant ceramic body that can withstand temperatures of up to 200°C, and the body is filled with an internal conductor such as an alloy (usually tin-lead) or a metal film. The conductor material is chosen to provide the necessary resistance for the circuit, according to Ohm\'s law.

The RN55E4643BBSL is a through hole, axial leaded resistor that is rated for a power dissipation of up to 3.0W at 70°C. It is made using a manganese dioxide fired ceramic body, which is then coated with a flame retardant material. The conductor is composed of tin-lead alloy, with a resistive value of 4.643 Ohms. The package size is 0.125 inch by 0.120 inch, and the pins are rated for a solder heat dissipation of up to 260°C.

The RN55E4643BBSL is designed for use in a wide range of applications such as power supplies, automotive electronics, medical equipment, telecommunications systems, and consumer electronics. Its resistance value is typically used in conjunction with other components to create a desired circuit. For example, it can be used in a voltage divider circuit, where it will divide the input voltage into two parts. In each branch of the circuit, the RN55E4643BBSL will provide the necessary resistance to ensure that the desired output voltage is achieved. It can also be used in a current-limiting configuration, where it will protect sensitive components from over-current conditions.

In addition to providing the necessary resistance for a given circuit, the RN55E4643BBSL can also be used to protect the circuit board and other components from the risk of electrical fires. Due to the heat-resistant ceramic body, it can withstand temperatures up to 200°C without damaging the board or other components. As an added benefit, the flame-retardant coating provides additional protection against fire hazards, allowing the resistor to be used in high-temperature environments. The internal conductor also helps to dissipate heat quickly, keeping the temperature of the component below its rated maximum.

The RN55E4643BBSL is a versatile through hole resistor that is suitable for use in a variety of applications. Its heat-resistant ceramic body and flame-retardant coating make it well-suited for applications in high-temperature environments, and its internal conductor helps to dissipate heat quickly. It is an ideal choice for voltage and current-limiting configurations, as well as for protecting the board and other components from fire hazards. As a result, the RN55E4643BBSL is a reliable and effective resistor for a variety of circuit designs.
