ERJ-3EKF4702V Series

series introduction

# ERJ - 3EKF4702V Product Series Introduction

## 1. Overview
The ERJ - 3EKF4702V product series is a remarkable line of electronic components that offers high - performance and reliability in various electronic applications. These components are engineered with precision to meet the demanding requirements of modern electronic circuits, providing stable and accurate electrical characteristics.

## 2. Product Specifications

### 2.1 Resistance Value
The "4702" in the model number indicates the resistance value. Using the standard resistor code system, where the first three digits represent significant figures and the last digit is the multiplier, for ERJ - 3EKF4702V, the resistance value is calculated as 470 × 10² = 47,000 ohms or 47 kΩ. This specific resistance value makes it suitable for a wide range of applications where precise resistance is crucial, such as in voltage dividers, signal conditioning circuits, and current - limiting applications.

### 2.2 Tolerance
The series typically offers a tight tolerance, which means the actual resistance value of the component will be very close to the specified 47 kΩ. A common tolerance level for this series might be ±1%. This high - precision tolerance ensures that the circuit performance is consistent and predictable, reducing the margin of error in electronic designs.

### 2.3 Power Rating
The power rating of the ERJ - 3EKF4702V series is designed to handle a certain amount of electrical power without overheating or getting damaged. For example, it may have a power rating of 1/16 watt or 0.0625 watt. This power rating determines the maximum amount of power that the resistor can safely dissipate, and it is an important consideration when designing circuits to ensure that the component operates within its safe limits.

### 2.4 Temperature Coefficient
The temperature coefficient of resistance (TCR) is another important specification. A low TCR value indicates that the resistance of the component changes minimally with temperature variations. The ERJ - 3EKF4702V series may have a relatively low TCR, such as ±100 ppm/°C. This characteristic is essential in applications where the circuit needs to maintain stable performance over a wide temperature range, such as in automotive electronics, industrial control systems, and aerospace applications.

## 3. Physical Characteristics

### 3.1 Package Size
The ERJ - 3EKF4702V series comes in a compact surface - mount package. The small size makes it ideal for use in printed circuit boards (PCBs) with limited space, such as in mobile devices, wearables, and other miniaturized electronic products. The package is designed for easy soldering onto the PCB, ensuring a reliable electrical connection.

### 3.2 Construction
These resistors are constructed using high - quality materials and advanced manufacturing processes. The resistive element is typically made of a thin - film material, which offers excellent stability and low noise characteristics. The outer coating provides protection against environmental factors such as moisture, dust, and mechanical stress, ensuring the long - term reliability of the component.
