series introduction
# Introduction to the CRCW060347K0FKEA Product Series
## 1. Overview
The CRCW060347K0FKEA belongs to a specific series of surface - mount resistors. These resistors are crucial components in modern electronic circuits, playing a fundamental role in controlling current flow, voltage division, and signal attenuation. The "CRCW" is often a part number prefix that indicates the resistor's series or family, while "0603" refers to the physical size of the resistor, and "47K0" represents its resistance value. The "F" and "KEA" are likely related to tolerance, temperature coefficient, and other specific characteristics of the product.
## 2. Physical Characteristics
### Size and Dimensions
The 0603 size is a standard in the surface - mount technology (SMT) industry. It has a length of approximately 1.6 mm and a width of about 0.8 mm. This compact size makes it suitable for use in densely populated printed circuit boards (PCBs), such as those found in mobile devices, wearables, and other miniaturized electronics. The small footprint allows for high - density component placement, enabling the design of smaller and more lightweight electronic products.
### Packaging
These resistors are typically supplied in tape - and - reel packaging. This packaging method is ideal for automated pick - and - place machines used in mass - production PCB assembly lines. The resistors are arranged in a continuous tape, which is wound onto a reel, ensuring easy handling and efficient integration into the manufacturing process.
## 3. Electrical Characteristics
### Resistance Value
The resistance value of the CRCW060347K0FKEA is 47 kΩ (47,000 ohms). This value is carefully calibrated during the manufacturing process to meet specific application requirements. Resistors with this value can be used in a variety of circuits, such as voltage dividers, where they help to create a specific voltage level from a higher input voltage. For example, in a simple voltage - dividing circuit with a 10 - volt input, a 47 kΩ resistor can be combined with another resistor to output a desired lower voltage.
### Tolerance
The "F" in the part number usually indicates a tolerance of ±1%. This means that the actual resistance value of the resistor can vary by up to 1% from the nominal value of 47 kΩ. A tight tolerance is important in applications where precise resistance values are required, such as in precision measurement circuits, audio amplifiers, and some types of sensor interfaces. For instance, in a sensor circuit, a small deviation in resistance can lead to inaccurate readings, so a resistor with a low tolerance is essential.
### Temperature Coefficient
The temperature coefficient of the resistor affects how its resistance value changes with temperature. Although the specific temperature coefficient is not directly indicated by the given part number, it is an important parameter. A low temperature coefficient means that the resistance value remains relatively stable over a wide range of temperatures. This is crucial in applications where the operating temperature can vary significantly, such as in automotive electronics, industrial control systems, and outdoor - use devices.
### Power Rating
The power rating of the CRCW060347K0FKEA is typically designed to handle a certain amount of power without overheating. For a 0603 - sized resistor, the power rating is usually in the range of 1/16 watt to 1/10 watt. This power rating determines the maximum amount of power that the resistor can dissipate safely. In a circuit, if the power dissipated by the resistor exceeds its rating, it can lead to overheating, which may cause the resistor to fail or affect the performance of the entire circuit.
