Through Hole Resistors, like the PWR220T-35-4700J, adhere to a basic principle for operation. The resistance element is made of a material, like metal, that has a stable electrical resistance. When a voltage is applied, the current that flows through the resistance material is proportional to the voltage, and that current is limited to the resistance of the material. The voltage drop would be equal to the resistance of the element multiplied by the current, so in this example, the PWR220T-35-4700J would have a voltage drop of 0.322 volts at a supplied current of 25 mA.

The through hole resistors, such as PWR220T-35-4700J, have various range of values and vary in power rating. This particular resistor has a value of 4700 ohms and a power rating of 220 mW. In addition, it has rated voltage of 35V with a withstanding voltage of 50V. Depending on the application, the choice of through hole resistor will vary. Its heat sink tab adds another dimension to the choice, particularly given that through hole resistors dissipate nearby heat due to their close proximity to other transistors and chips.

The range of power ratings of through hole resistors available range from 1/16 W up to 5 W. When selecting a through hole resistor for a particular application, it is important to consider the power that will be dissipated. As the power rating of the resistor is raised, the resistance value is decreased to account for the additional power. Through hole resistors are mostly used when space is not a major concern. However, as the power rating increases, its size expands and it consumes more space.

The PWR220T-35-4700J is primarily used for connection protection due to its relative small size, good power rating, high voltage rating, and strong withstanding voltage. This through hole resistor provides protection against high voltages, as noted by its rated and withstanding voltages. The rated voltage of the resistor is typically the maximum voltage that may pass through the collector for unlimited lengths of time, and the withstanding voltage is the maximum voltage that the resistor can withstand before it breaks down. Connecting the resistor directly to a sensitive and expensive component can limit the connection to a certain voltage.

Also, the PWR220T-35-4700J through hole resistor provides protection against high current and overheating. The resistance element essentially limits the current, and the greater the resistance value, the lower the current that flows through the resistor. Additionally, these are typically designed with a heat sink tab that dissipates heat due to the close proximity to other transistors and chips. This stops the resistor from failing as a result of heat problems.

All in all, the PWR220T-35-4700J through hole resistor is one of the preferred resistors for connection protection and voltage regulation. Its relatively small size, good power rating, high voltage rating, and strong withstanding voltage makes it ideal for use in many applications. In addition, its large resistance range means that it can be used in high voltage applications, as well as for current and heat regulation. With the right features and the right application, this through hole resistor can provide reliable and accurate connection protection and voltage regulation.
