series introduction

# Introduction to the CRCW080533R0JNEA Product Series

## 1. Overview
The CRCW080533R0JNEA 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, dividing voltages, and setting signal levels. The "CRCW" is often the product family code, "0805" refers to the physical size of the resistor according to the industry - standard surface - mount package, "33R0" indicates the resistance value, and "JNEA" might represent specific tolerance, temperature coefficient, and other electrical and manufacturing - related characteristics.

## 2. Physical Characteristics

### 2.1 Package Size
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. The small footprint allows for high - density circuit board designs, enabling manufacturers to pack more functionality into a smaller area.

### 2.2 Construction
The resistor is typically constructed using a thin - film technology. A thin layer of resistive material is deposited on a ceramic substrate. This construction provides several advantages, including good stability, low noise, and excellent temperature coefficient characteristics. The ceramic substrate offers high mechanical strength and good thermal conductivity, which helps in dissipating heat generated during operation.

## 3. Electrical Characteristics

### 3.1 Resistance Value
The resistance value of the CRCW080533R0JNEA is 33 ohms. This value is carefully calibrated during the manufacturing process to meet the specified tolerance. The 33 - ohm resistance can be used in a variety of applications, such as in current - limiting circuits, where it restricts the amount of current flowing through a particular part of the circuit to protect sensitive components from over - current damage. It can also be used in voltage - dividing circuits, where it helps in creating a specific voltage level from a higher input voltage.

### 3.2 Tolerance
The "J" in the part number usually indicates a tolerance of ± 5%. This means that the actual resistance value of the resistor can vary within ± 5% of the nominal 33 - ohm value. For example, the actual resistance could range from 31.35 ohms (33 - 0.05×33) to 34.65 ohms (33+ 0.05×33). A 5% tolerance is suitable for many general - purpose electronic applications where a high degree of precision is not required.

### 3.3 Temperature Coefficient
The temperature coefficient of resistance (TCR) is an important parameter that describes how the resistance value changes with temperature. The specific TCR for the CRCW080533R0JNEA is determined by the "NEA" part of the code. A low TCR indicates 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 or industrial control systems.

### 3.4 Power Rating
The power rating of the 0805 - sized resistor is typically around 0.125 watts. This means that the resistor can safely dissipate up to 0.125 watts of power without overheating. When using the resistor in a circuit, it is important to ensure that the power dissipated across it does not exceed this rating to prevent damage to the component.
