R3J3K9E

A Through Hole Resistor (also known as a power resistor or THP resistor) is an electronic component designed to resist or limit the flow of electricity from a given source to a certain level. Through Hole Resistors are commonly used in power supplies, audio systems, circuits, and other components within a circuit to prevent or protect against overloading. The main components of a Through Hole Resistor are an insulated material with variable resistance and a dielectric material with properties that can be fine-tuned to the desired output. THP resistors typically have an inscription (banding) on the body itself to identify the resistance value, and may also have additional features to allow the user to change the tolerance, stabilizing or buffering voltage levels.

R3J3K9E is a Through Hole Resistor specifically designed to provide a 20% tolerance over the resistance range of 3 to 39KΩ. It has a temperature coefficient of ±100ppm/°C, an operating temperature range of -55°C to +155°C, an insulation voltage of 300V, and a maximum overload voltage of 450V. This makes R3J3K9E a reliable and robust resistor that can be used in a range of applications. Its size and form factor also make it an ideal choice for precision circuit assemblies.

R3J3K9E is commonly used in automotive, medical, industrial, and aviation applications where extreme temperature ranges, air insulation, or high reliability is necessary. Its construction offers tighter tolerances over a wide resistance range, making it suitable for a variety of monitoring and control circuits. For example, in automotive applications, this resistor can be used in fuel injection systems, ABS control systems, and brake controls, where precise and repeatable resistances are necessary. In industrial applications, it can be used in robotics, data centers, instrumentation, and power generation applications. In medical applications, its reliable tolerance and high air insulation makes it suitable in measurement and control circuits for patient monitoring equipment.

The R3J3K9E’s working principle is based on the fact that when a voltage is applied across it, a current will flow through the resistor. This current is determined by the amount of resistance created by the resistor. The formula for calculating the current through a resistor, the Ohm\'s law, states that:

I = V/R

Where I is the current, V is the applied voltage, and R is the resistance. The resistance of the R3J3K9E resistor is determined by its resistance value, which is provided by its inscription (banding). The voltage applied across the resistor will determine the current that will flow through it, the greater the voltage, the greater the current. Further, the resistance is affected by temperature changes, therefore, its temperature coefficient should be taken into consideration when calculating the current, and should always be within the specified range.

In conclusion, the R3J3K9E is a Through Hole Resistor designed to provide a reliable and repeatable resistance over a wide range of applications. Its tight tolerance, temperature coefficient stability, and high air insulation make it a suitable choice for automotive, medical, industrial, or aviation applications. The working principle of the R3J3K9E is based on the Ohm\'s law equation, which states that the current through the resistor is determined by the voltage applied across it and the resistance of the resistor.
