series introduction
# Introduction to the CRCW080536K5FKT Product Series
## 1. Overview
The CRCW080536K5FKT 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" indicates the package size, "36K5" represents the resistance value, and "FKT" is related to the resistor's tolerance and other specific characteristics.
## 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
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 production efficiency and reduces manufacturing costs. The flat surface of the package ensures good contact with the PCB pads, providing reliable electrical connections.
## 3. Resistance Value (36K5)
### Meaning
The "36K5" notation represents a resistance value of 36.5 kΩ (kilo - ohms). Resistance is a fundamental electrical property that opposes the flow of electric current. In a circuit, a 36.5 kΩ resistor can be used in various applications, such as biasing transistors, setting the gain of amplifiers, or as part of a voltage - dividing network.
### Accuracy
The resistance value of the CRCW080536K5FKT is specified with a certain level of accuracy. This accuracy is crucial in circuits where precise current and voltage control are required. For example, in sensor circuits, an accurate resistance value ensures that the sensor output is correctly calibrated.
## 4. Tolerance and Temperature Coefficient
### Tolerance
The "F" in the "FKT" code typically indicates a tolerance of ±1%. Tolerance refers to the allowable deviation of the actual resistance value from the specified value. A ±1% tolerance means that the actual resistance of the CRCW080536K5FKT resistor will be within 1% of the nominal 36.5 kΩ value. This high - precision tolerance makes the resistor suitable for applications where tight control of electrical parameters is necessary, such as in precision measurement equipment and high - end audio circuits.
### Temperature Coefficient
The temperature coefficient of resistance (TCR) is another important characteristic. Although not explicitly shown in the "CRCW080536K5FKT" code, these resistors usually have a relatively low TCR. A low TCR means that the resistance value changes minimally with temperature variations. This is essential in applications where the operating temperature may fluctuate, as it helps maintain the stability of the circuit's performance. For example, in automotive electronics, where the temperature can range from extremely cold to very hot, a resistor with a low TCR ensures reliable operation.
## 5. Power Rating
The power rating of the CRCW080536K5FKT is determined by its physical size and construction. For an 0805 - sized resistor, the typical power rating is around 1/8 watt (0.125 W). The power rating indicates the maximum amount of power that the resistor can safely
