Through hole resistors are a type of resistor with leads that are designed to be inserted into a hole in the printed circuit board (PCB). They are generally used to limit the current in circuits or to reduce voltage spikes. The most commonly used types are wirewound, carbon composition, and chip resistors. H4681RBCA is one of the most popular through hole resistors available on the market today.

The H4681RBCA is a 1W (1 watt) through hole resistor. It has a 4-pin configuration with a 0603 size package. The resistor is made of a carbon composite and uses a wirewound construction. The resistive element is constructed from a thin, tightly enveloped wire, which is soldered to the leads at one end, while the other end is connected to the copper trace on the PCB.

The H4681RBCA is well suited for applications in which power dissipation needs to be controlled. This type of resistor is typically used in power control circuits such as DC motors, camera shutters, and heating elements. The H4681RBCA is also commonly used in high-frequency circuits such as RF amplifiers and mixers, audio amplifiers, and switching regulators.

The working principle of the H4681RBCA is based on the conversion of electric energy into heat energy. When an electric current passes through the resistor, some of the energy is converted into heat due to the resistance of the material. As a result, the temperature of the resistor increases, causing a decrease in resistance. This process is known as “self-heating”, and is the basis of the H4681RBCA’s function.

The H4681RBCA can handle up to 1 watt of power dissipation. This is due to its construction, which utilizes a thin, tightly enveloped wire to maximize heat dissipation. The resistor is designed to operate at a maximum temperature of 150°C, making it suitable for most through-hole applications. Additionally, the H4681RBCA has a wide operating temperature range of -55°C to +150°C.

The H4681RBCA is a reliable and durable through hole resistor, making it well suited for a variety of applications. Its ability to accurately limit current or reduce voltage spikes makes it an ideal choice for industrial, consumer, and automotive circuits. The resistor is also easy to install, as it requires no additional soldering. Furthermore, its small size makes it ideal for applications where space is limited.

In conclusion, the H4681RBCA is an incredibly versatile through hole resistor designed to handle up to 1 watt of power. It features a wide operating temperature range and is suitable for a variety of applications. Its reliable and durable construction, combined with its easy-to-install design, makes it the perfect choice for professional electronic projects.
