Through hole resistors (THRs) offer a wide variety of applications in various fields. A major advantage of the THR is that it can provide a very high resistance in a very small package. This allows it to be used in a wide variety of applications such as power supplies, surge protectors, audio applications and other forms of signal processing. An example of the THR, specifically the H811R3BCA application, is discussed below.

The H811R3BCA is a THR based on PTC (Positive Temperature Coefficient) technology. It is used for current limiting and is suitable for applications such as automotive, industrial, audio, and many other applications. The device contains a cylindrical sleeve which functions as an air gap to shield the resistor from thermal runaway and undesired overvoltage conditions.

The working principle of the H811R3BCA is based on the fact that when a current passes through the resistor, the current will cause the material to heat up. The amount of heat generated will depend on the current passing through the resistor as well as the material used in its construction. The material will expand when it is heated, thereby increasing the resistance of the resistor. The amount of current that is allowed to pass through the resistor can be adjusted by altering the resistance of the device, thus providing a level of current limiting protection.

The H811R3BCA is ideal for use in automotive, industrial, and audio applications, as it can provide reliable protection against over-current conditions. It can also be used in applications such as surge protection, where the device can protect electronic components from electrical over-stress or from transient voltage spikes. Additionally, the H811R3BCA is also effective in providing current limiting and thermal protection to portable electronic devices such as mobile phones, personal digital assistants, and laptops. It can also be used to protect medical equipment from lightning and other over-voltage events.

In summary, the H811R3BCA THR is an ideal device for a variety of applications due to its ability to provide effective and reliable current limiting and thermal protection. The device is based on PTC technology and uses an air gap to shield it from thermal runaway and undesired overvoltage conditions. It is suitable for automotive, industrial, audio, and other applications, and can provide vital protection from over-current and over-voltage events.
