series introduction

# X7R0402 Product Series Introduction

## 1. Overview
The X7R0402 product series represents a cutting - edge range of electronic components, specifically ceramic capacitors. These capacitors are designed to meet the diverse and demanding requirements of modern electronic circuits, offering a balance of performance, reliability, and compactness. The "0402" in the series name refers to the industry - standard package size, which measures 0.04 inches by 0.02 inches (1.0mm x 0.5mm), making them ideal for applications where space is at a premium. The "X7R" designation indicates the dielectric type, which is known for its excellent temperature stability and relatively high capacitance values.

## 2. Key Features

### 2.1 Capacitance Range
The X7R0402 series offers a wide range of capacitance values, typically spanning from a few picofarads (pF) to several hundred nanofarads (nF). This broad range allows designers to select the appropriate capacitance for their specific circuit requirements, whether it's for high - frequency filtering, decoupling, or timing applications.

### 2.2 Temperature Stability
One of the standout features of the X7R dielectric is its exceptional temperature stability. The capacitance of X7R capacitors changes by no more than ±15% over a temperature range of - 55°C to +125°C. This makes the X7R0402 series suitable for use in environments with significant temperature variations, such as automotive electronics, industrial control systems, and aerospace applications.

### 2.3 Low Equivalent Series Resistance (ESR)
The X7R0402 capacitors have a low ESR, which is crucial for high - frequency applications. A low ESR value means that the capacitor can efficiently store and release electrical energy, reducing power losses and improving the overall performance of the circuit. This is particularly important in power supply circuits, where low ESR capacitors help to filter out high - frequency noise and ripple.

### 2.4 High Voltage Rating
Despite their small size, the X7R0402 series offers a relatively high voltage rating. Capacitors in this series can typically withstand voltages ranging from a few volts to several hundred volts, depending on the specific capacitance value. This high voltage rating makes them suitable for use in a variety of power - related applications, including voltage regulation and energy storage.

### 2.5 RoHS Compliance
All products in the X7R0402 series are compliant with the Restriction of Hazardous Substances (RoHS) directive. This means that they are free from harmful substances such as lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBBs), and polybrominated diphenyl ethers (PBDEs), making them environmentally friendly and suitable for use in global markets.

## 3. Applications

### 3.1 Consumer Electronics
In consumer electronics, such as smartphones, tablets, and wearables, the X7R0402 series is widely used for decoupling and filtering applications. Their small size allows for high - density circuit board designs, while their excellent electrical performance helps to ensure the stable operation of the device. For example, they can be used to filter out power supply noise in the audio and video circuits of a smartphone, improving the overall sound and image quality.

### 3.2 Automotive Electronics
Automotive electronics require components that can withstand harsh environmental conditions, including high temperatures, vibrations, and electrical noise. The X7R0402 series meets these requirements with its temperature stability and high - voltage rating. They are used in various automotive systems, such as engine control units (ECUs), infotainment systems, and advanced driver -
