# Introduction to the RC0603JR - 07470RL Product Series
## 1. Overview
The RC0603JR - 07470RL belongs to a specific range of electronic components, more precisely, it is a surface - mount resistor. Surface - mount resistors are crucial in modern electronic circuits due to their compact size and high - performance characteristics. This particular product series is designed to meet the diverse needs of various electronic applications, offering reliable resistance values and excellent electrical properties.
## 2. Physical Characteristics
### 2.1 Package Size
The "0603" in the product code indicates the package size of the resistor. In the imperial measurement system, a 0603 package has dimensions of approximately 0.06 inches (1.6 mm) in length and 0.03 inches (0.8 mm) in width. This small form factor makes it ideal for use in densely populated printed circuit boards (PCBs), where space is often at a premium. It allows for the design of more compact and lightweight electronic devices, such as mobile phones, tablets, and wearable devices.
### 2.2 Construction
The resistor is constructed using high - quality materials to ensure stability and durability. The resistive element is typically made of a thin film or thick film material, which is deposited on a ceramic substrate. The ceramic substrate provides excellent thermal stability and mechanical support, while the resistive film determines the resistance value of the component. The ends of the resistor are terminated with metal electrodes, which are used for soldering the component onto the PCB.
## 3. Electrical Characteristics
### 3.1 Resistance Value
The "470R" in the product code indicates the resistance value of the resistor, which is 470 ohms. This resistance value is a standard value within the E - series of preferred numbers, which are commonly used in the electronics industry to ensure compatibility and interchangeability of components. A 470 - ohm resistor can be used in a variety of applications, such as current limiting, voltage division, and signal attenuation.
### 3.2 Tolerance
The "JR" in the product code indicates the tolerance of the resistor. In this case, the tolerance is ± 5%. Tolerance refers to the allowable deviation from the nominal resistance value. A ± 5% tolerance means that the actual resistance value of the resistor can vary between 446.5 ohms (470 - 470×0.05) and 493.5 ohms (470 + 470×0.05). This level of tolerance is suitable for many general - purpose electronic applications where a high degree of precision is not required.
### 3.3 Power Rating
The power rating of the RC0603JR - 07470RL is typically 1/16 watt. The power rating indicates the maximum amount of power that the resistor can safely dissipate without being damaged. When using the resistor in a circuit, it is important to ensure that the power dissipated by the resistor does not exceed its power rating. Otherwise, the resistor may overheat, which can lead to a change in its resistance value or even permanent damage.
### 3.4 Temperature Coefficient
The temperature coefficient of resistance (TCR) is an important parameter that describes how the resistance value of a resistor changes with temperature. Although the specific TCR value is not explicitly mentioned in the product code, typical values for resistors in this package size and type range from ± 100 ppm/°C to ± 200 ppm/°C. A lower TCR value indicates better stability over a wide temperature range, which is important in applications where the operating temperature may vary significantly.
