ERJ-1GEJ104C Series

series introduction

# ERJ - 1GEJ104C Product Series Introduction

## 1. Overview
The ERJ - 1GEJ104C belongs to a specialized series of electronic components, specifically resistors. These resistors are engineered to meet the diverse and demanding requirements of modern electronic circuits. With a focus on precision, reliability, and performance, the ERJ - 1GEJ104C series plays a crucial role in a wide range of applications, from consumer electronics to industrial control systems.

## 2. Key Specifications

### Resistance Value
The "104" in the model number indicates the resistance value. Using the standard resistor code system, 104 translates to a resistance of 100,000 ohms or 100 kΩ. This specific resistance value makes it suitable for various voltage - dividing, current - limiting, and signal - conditioning applications within electronic circuits.

### Tolerance
The series typically offers a tight tolerance. For the ERJ - 1GEJ104C, it often has a tolerance of ±5%. This means that the actual resistance value of each resistor in the series will deviate by no more than 5% from the nominal 100 kΩ value. A low tolerance is essential in applications where precise resistance values are required for accurate circuit operation, such as in analog circuits and sensor interfaces.

### Power Rating
These resistors are designed with a specific power rating. The ERJ - 1GEJ104C usually has a power rating of 1/16 watt. This power rating determines the maximum amount of power the resistor can safely dissipate without overheating or experiencing significant changes in its electrical properties. It is an important consideration when designing circuits to ensure that the resistor can handle the power requirements of the application.

### Temperature Coefficient
The temperature coefficient of resistance (TCR) is another critical specification. The ERJ - 1GEJ104C series typically has a relatively low TCR, which means that the resistance value changes minimally with temperature variations. A low TCR helps maintain the stability of the circuit performance over a wide temperature range, making these resistors suitable for applications in environments with fluctuating temperatures, such as automotive electronics and outdoor equipment.

## 3. Physical Characteristics

### Package Type
The ERJ - 1GEJ104C is commonly available in a surface - mount device (SMD) package. SMD packages are popular in modern electronics due to their small size, which allows for high - density circuit board designs. The compact size also reduces the overall footprint of the circuit, making it ideal for portable devices and miniaturized electronic products.

### Dimensions
The specific dimensions of the SMD package are carefully designed to ensure compatibility with standard pick - and - place equipment used in automated circuit board assembly. This standardization simplifies the manufacturing process and reduces production costs.

### Color and Markings
The resistors are usually marked with their resistance value and other relevant information using a color - coding system or laser - etched markings. These markings make it easy for technicians and engineers to identify the resistor's specifications during circuit assembly and troubleshooting.

## 4. Performance Advantages

### High Precision
Thanks to its tight tolerance and low TCR, the ERJ - 1GEJ104C series offers high - precision performance. This precision is crucial in applications such as audio amplifiers, where accurate resistance values are necessary to achieve the desired sound quality, and in measurement instruments, where precise signal conditioning is required for accurate readings.

### Reliability
The resistors are manufactured using high - quality materials and advanced production processes, ensuring long - term reliability. They are designed to withstand various environmental stresses, such as humidity, temperature cycling, and mechanical vibrations. This reliability makes them suitable for use in critical applications where component failure can
