Through hole resistors are one of the most common electronic components used in electrical and electronic circuits. They are also referred to as “fixed resistors” as they have a fixed resistance value in ohms. They come in a variety of physical packages and serve a wide range of applications. The RWR78S2R15FRB12 is one such through hole resistor with a range of application fields and a unique working principle.

The RWR78S2R15FRB12 is constructed with an aluminum-nitride ceramic core that is actively cooled by a built-in fan. The core contains two serpentine coils, and connected in series, forming a three-dimensional electrical field. The resistor has a continuous current rating of up to 2 Amps, making it suitable for high power applications. The wide temperature range ( -55°C to +125°C ) makes it an excellent choice for use in extreme environments. The resistor is also designed for low EMI/RFI susceptibility to reduce interference.

The RWR78S2R15FRB12 is capable of a wide range of applications, including radio-frequency circuitry, digital interfaces, and power circuits. Its capability to control high power levels makes it ideal for use in high power and high frequency circuits. It is also suited to applications that involve heavy duty loads, such as high power amplifiers and power supplies. Due to the active fan cooling and the reliable temperature range, the RWR78S2R15FRB12 is well suited for use in automotive, aerospace, and military applications.

The working principle of the RWR78S2R15FRB12 is based on the use of an internal series connection of two serpentine coils. When a current passes through the resistor, the coils generate a three-dimensional electrical field. This field is stronger at the ends of the coils, creating a higher resistance at those points. This higher resistance translates into a lower current flow through the resistor. The voltage drop across the resistor is determined by the amount of current flowing through it.

The fan cooling of the RWR78S2R15FRB12 helps to keep the core temperature constant, allowing the resistor to achieve better performance. This is especially important in applications involving high power loads. The RWR78S2R15FRB12 has a long life span, making it well suited for long-term applications. Another advantage of this resistor is its low EMI/RFI susceptibility, which helps to reduce interference.

In conclusion, the RWR78S2R15FRB12 is a through hole resistor with a wide range of applications and a unique working principle. The active cooling fan, wide temperature range, and low EMI/RFI susceptibility make it an ideal choice for a variety of applications. The resistor can be used in high power and high frequency circuits, automotive, aerospace, and military projects. Its unique working principle and long life span make it an excellent choice for long-term applications such as radio-frequency circuitry, digital interfaces, and power circuits.
