series introduction
# Introduction to the CRCW08051K00FKEA Product Series
## 1. Overview
The CRCW08051K00FKEA belongs to a specific series of surface - mount resistors. These resistors are an essential component in modern electronic circuits, playing a crucial role in controlling current flow, voltage division, and signal attenuation. The "CRCW" is the product family code, "0805" refers to the package size, "1K00" indicates the resistance value, and "FKEA" may represent additional features or specific manufacturing codes within the series.
## 2. Package Size (0805)
### Physical Dimensions
The 0805 package is a widely used standard in the electronics industry. It has a length of approximately 2.03 mm and a width of about 1.27 mm. This relatively small size makes it suitable for use in compact electronic devices where space is at a premium, such as mobile phones, tablets, and wearable devices.
### Mounting
The surface - mount design of the 0805 package allows for automated assembly processes. It can be easily placed on a printed circuit board (PCB) using pick - and - place machines, which significantly increases the manufacturing efficiency and reduces production costs. The flat bottom surface of the resistor ensures good contact with the PCB pads, providing stable electrical connections.
## 3. Resistance Value (1K00)
### Nominal Resistance
The nominal resistance value of the CRCW08051K00FKEA is 1000 ohms (1 kΩ). This value is carefully calibrated during the manufacturing process to meet specific electrical requirements. In a circuit, a 1 kΩ resistor can be used in various applications. For example, it can be used as a pull - up or pull - down resistor in digital circuits to ensure proper logic levels. In analog circuits, it can be part of a voltage divider network to obtain a specific output voltage.
### Tolerance
The "F" in the part number typically indicates a tolerance of ±1%. This means that the actual resistance value of the resistor can vary within 1% of the nominal value. For a 1 kΩ resistor with a ±1% tolerance, the actual resistance can range from 990 ohms to 1010 ohms. A low - tolerance resistor like this is suitable for applications where precise resistance values are required, such as in precision measurement circuits or high - performance audio amplifiers.
## 4. Electrical Characteristics
### Power Rating
The CRCW08051K00FKEA has a specific power rating. For the 0805 package, the typical power rating is around 0.125 W. This power rating determines the maximum amount of power that the resistor can safely dissipate without overheating. When using the resistor in a circuit, it is important to ensure that the power dissipated across the resistor does not exceed its rated power. Otherwise, the resistor may experience a change in resistance value due to overheating or even fail completely.
### Temperature Coefficient
The temperature coefficient of resistance (TCR) is another important electrical characteristic. It indicates how the resistance value of the resistor changes with temperature. A low TCR value means that the resistance is relatively stable over a wide temperature range. The CRCW08051K00FKEA is designed to have a low TCR, which makes it suitable for use in environments where the temperature may vary, such as automotive electronics or industrial control systems.
