Through Hole Resistors have existed for many decades, but their usefulness continues to evolve as technology advances. RR03J51RTB is one such example of a device used in many applications. This device is a non-inductive, four-terminal, axial-lead resistor. It is composed of two outer terminals and two inner terminals. The inner terminals are connected through a non-inductive medium, such as a ceramic core or a mica-core.

RR03J51RTB application field mainly includes high-frequency power supplies, attenuators, and high-order noise filters. Its applications in these fields include high-frequency waveforms and linear waveforms, and it is also used in high "Q" applications, such as fabricating an inductor by winding a wire coil in the presence of an iron core for matching. Widely used for precision instrumentation and audio equipment, RR03J51RTB is also suitable for antiparallel networks and low pass filter networks. Inside the audio industry, this device is used for synthesizers, amplifiers, mixers, and other audio circuitry.

RR03J51RTB has a wide range of operating temperatures, making it suitable for use in many different environments. It can operate from -55 Celsius degrees to +150 Celsius degrees Celsius. This device also limits voltage surges, making it able to cope with sudden, unexpected power changes. RR03J51RTB boasts a long life expectancy, in some cases lasting up to 1,000 cycles. It can also be used in series with other components in many circuits for voltage divider functions, where its low inductance and multitude of terminals are ideal for this purpose.

The RR03J51RTB’s working principle relies on its resistance, which is defined as the opposition between the current and the voltage of a device, causing a decrease in the current flow. This resistance is determined by the material used in its construction, which is typically a ceramic or mica core surrounded by an oxidized metal material, such as silver, tin, and lead. To obtain precision current flows, the inner terminals are used to apply current into the resistor, which then enters the core material and dissipates over its length. As the current enters the metal, electrons flow in the opposite direction, creating a ‘backpressure’ that is then applied to the outer terminals, thus controlling and limiting the current flow.

The RR03J51RTB is an invaluable component in many electrical applications. Its ability to withstand extreme temperatures, its resistance at high frequency, and its ability to provide precision voltage ratings are some of its most significant features. Furthermore, its small size and relatively low cost make it attractive from a manufacturing stand-point. Suitable for both the consumer and industrial market, the RR03J51RTB is an ideal resistor for those seeking quality and reliability.
