Through Hole Resistors are a type of electrical resistor that are wired into circuit boards from the top of the board with two leads that go through the hole. The PWR4412-2SBR1000F is a through hole resistor that is designed for use in a variety of different applications. It is a radial leaded non-inductive high-power rated Wirewound Power Resistor. It is usually used in high-frequency applications and high-power applications due to its resistor construction and lead configuration.

The PWR4412-2SBR1000F is a 4-terminal radial leaded non-inductive wirewound power resistor. The resistor element consists of a winding of manganin wire which is wound around a high temperature epoxy coated ceramic core. This type of construction ensures a very uniform winding for high frequency applications and also helps resist ambient temperature spikes. The PWR4412-2SBR1000F provides high power dissipation in a small package while also providing a low TCR of 25ppm/°C for improved stability.

The 4-terminal configuration of the PWR4412-2SBR1000F makes it ideal for applications that require power routing with high frequency signals. The two leads are connected to the winding and the remaining two terminals are designed for power routing. The two leads are connected to terminals 1 and 4 while the two power routing terminals are connected to terminals 2 and 3. This allows for a more efficient power routing, as the power current has two paths instead of one.

The PWR4412-2SBR1000F is designed to handle current ratings of up to 1A and power ratings up to 250W. The power ratings of the resistor are determined by its thermal capacity, its power rating at rated voltage, and its dissipation factor. It is usually rated for an operating temperature of up to 150°C. The resistor also has a low resistance-temperature coefficient of 25ppm/°C, allowing for improved temperature stability over time.

The PWR4412-2SBR1000F has a wide range of applications. It is often used in high-frequency switching applications, such as inverters and motor control. It has also found a place in RF and high-temperature applications, such as in the automotive industry. Its 4-terminal construction makes it ideal for power routing and high frequency circuit use, providing efficient power routing in a small package.

In conclusion, the PWR4412-2SBR1000F is a through-hole resistor that is designed for use in high-power and high-frequency applications. It has a 4-terminal configuration which allows for efficient power routing. It has a maximum current rating of 1A and a maximum power rating of 250W, making it suitable for many applications. It is also designed to have a low TCR of 25ppm/°C, ensuring temperature stability over time. All these features make the PWR4412-2SBR1000F a great choice for many different applications.
