series introduction
# Introduction to the CRCW080582K5FKEA Product Series
## 1. Overview
The CRCW080582K5FKEA 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 often the product family code, "0805" refers to the package size, "82K5" indicates the resistance value, and "FKEA" may represent additional features or specific manufacturing codes.
## 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 (0.08 inches) and a width of about 1.27 mm (0.05 inches). 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 Advantages
The surface - mount design of the 0805 package allows for automated assembly processes. It can be easily placed on printed circuit boards (PCBs) using pick - and - place machines, which significantly increases the manufacturing efficiency and reduces production costs. Additionally, the surface - mount technology provides better electrical performance in high - frequency applications compared to through - hole components, as it reduces parasitic inductance and capacitance.
## 3. Resistance Value (82K5)
### Explanation of the Value
The resistance value of 82K5 means 82.5 kΩ (kilo - ohms). Resistance is a measure of how much a component opposes the flow of electric current. In a circuit, a resistor with an 82.5 kΩ value can be used in various applications. For example, in a voltage - divider circuit, it can be combined with other resistors to create a specific output voltage based on the input voltage and the ratio of the resistances.
### Tolerance
The "F" in the part number typically indicates a tolerance of ±1%. This means that the actual resistance value of the CRCW080582K5FKEA resistor can vary within 1% of the nominal 82.5 kΩ value. A low tolerance is important in applications where precise control of current and voltage is required, such as in precision measurement equipment, audio amplifiers, and sensor circuits.
## 4. Electrical Performance
### Power Rating
The power rating of the CRCW080582K5FKEA is an important parameter. It determines the maximum amount of power the resistor can safely dissipate without overheating. For the 0805 package, the typical power rating is around 1/8 watt (0.125 W). This power rating limits the amount of current that can flow through the resistor according to the power formula \(P = I^{2}R\) (where \(P\) is power, \(I\) is current, and \(R\) is resistance).
### Temperature Coefficient
The temperature coefficient of resistance (TCR) is another key electrical characteristic. It describes how the resistance value of the resistor changes with temperature. A low TCR is desirable in applications where the circuit needs to maintain stable performance over a wide temperature range. The CRCW080582K5FKEA usually has a relatively low TCR, ensuring that the resistance value remains relatively constant even as the temperature fluctuates.
## 5. Applications
### Consumer Electronics
In mobile phones and tablets, these resistors are used in power management circuits to control the charging and discharging of batteries, as well
