series introduction
# Introduction to the CRCW080547K0FKEA Product Series
## 1. Overview
The CRCW080547K0FKEA belongs to a specific series of surface - mount resistors. Surface - mount resistors are essential passive components in modern electronic circuits, and this particular series offers unique features and performance characteristics that make it suitable for a wide range of applications.
### Package Size
The "0805" in the part number indicates the package size of the resistor. In the imperial measurement system, an 0805 package has dimensions of approximately 0.08 inches (2.032 mm) in length and 0.05 inches (1.27 mm) in width. This relatively compact size makes it ideal for use in printed circuit boards (PCBs) where space is at a premium, such as in mobile devices, wearable electronics, and small - form - factor consumer electronics.
## 2. Electrical Specifications
### Resistance Value
The "47K0" in the part number represents the resistance value of the resistor. It has a resistance of 47 kΩ (47,000 ohms). This value is crucial as it determines the amount of current that will flow through a circuit when a certain voltage is applied, according to Ohm's Law (V = IR, where V is voltage, I is current, and R is resistance). A 47 kΩ resistor can be used in various applications such as voltage dividers, signal attenuation, and biasing circuits.
### Tolerance
The "F" in the part number indicates the tolerance of the resistor. In this case, it has a tolerance of ±1%. Tolerance refers to the allowable deviation from the nominal resistance value. A ±1% tolerance means that the actual resistance of the CRCW080547K0FKEA resistor can vary between 46.53 kΩ (47 kΩ - 1% of 47 kΩ) and 47.47 kΩ (47 kΩ+ 1% of 47 kΩ). This high - precision tolerance makes the resistor suitable for applications where accurate resistance values are required, such as in precision measurement circuits, audio amplifiers, and sensor interfaces.
### Temperature Coefficient
Although not explicitly shown in the part number, these resistors typically have a specified temperature coefficient. The temperature coefficient indicates how the resistance value changes with temperature. A low - temperature coefficient is desirable as it ensures that the resistance remains relatively stable over a wide temperature range. This is important in applications where the operating temperature can vary significantly, such as in automotive electronics, industrial control systems, and outdoor - use electronic devices.
## 3. Construction and Materials
### Substrate
The resistor is built on a ceramic substrate. Ceramic substrates offer excellent mechanical stability, high thermal conductivity, and good electrical insulation properties. They can withstand high temperatures and mechanical stress, which is essential for the reliability of the resistor in various operating environments.
### Resistive Element
The resistive element is typically made of a thin - film material. Thin - film resistors are known for their high precision, low noise, and good temperature stability. The thin - film technology allows for precise control of the resistance value during the manufacturing process, which contributes to the tight tolerance of the CRCW080547K0FKEA series.
### Terminations
The terminations of the resistor are made of a metal alloy. These terminations provide a reliable electrical connection between the resistor and the PCB. They are designed to have low contact resistance and good solderability, ensuring a stable and long - lasting connection during the PCB assembly process.
