# Introduction to the ECJ2YF1A475Z Product Series
## 1. Overview
The ECJ2YF1A475Z product series belongs to the realm of electronic components, specifically ceramic capacitors. These capacitors play a crucial role in a wide range of electronic circuits, offering reliable and efficient performance for various applications. The series is designed to meet the demanding requirements of modern electronic devices, providing stable capacitance values and excellent electrical characteristics.
## 2. Key Specifications
### Capacitance
The "475" in the product code indicates a capacitance value. Using the standard capacitor coding system, where the first two digits are significant figures and the third digit is the multiplier, 475 translates to 47 followed by 5 zeros in picofarads. So, the capacitance of the ECJ2YF1A475Z is 4.7 μF (microfarads). This relatively high capacitance value makes it suitable for applications that require energy storage and filtering of electrical signals.
### Voltage Rating
The "1A" in the code represents the voltage rating. In the capacitor coding convention, "1A" corresponds to a voltage rating of 100V. This means that the capacitor can safely operate in circuits where the voltage across it does not exceed 100 volts. It provides a good balance between capacitance and voltage handling capabilities, making it versatile for different power levels in electronic systems.
### Dielectric Material
The "YF" indicates the type of dielectric material used in the capacitor. The specific dielectric in this case offers certain advantages such as relatively high capacitance per unit volume, good temperature stability, and low equivalent series resistance (ESR). These properties contribute to the overall performance and reliability of the capacitor in various operating conditions.
### Tolerance
The "Z" at the end of the product code represents the capacitance tolerance. A "Z" tolerance typically means a capacitance tolerance of -20% to +80%. This relatively wide tolerance is acceptable in many applications where precise capacitance values are not critical, such as in power supply filtering circuits.
## 3. Physical Characteristics
### Package Size
The ECJ2YF1A475Z series is available in a standard surface - mount package. Surface - mount technology (SMT) allows for easy and automated assembly on printed circuit boards (PCBs). The compact size of the SMT package makes it suitable for use in modern, miniaturized electronic devices where space is at a premium.
### Dimensions
The exact dimensions of the capacitor depend on the specific package type within the series. However, in general, SMT ceramic capacitors of this type are designed to be small and lightweight, enabling high - density PCB layouts.
### Temperature Range
These capacitors are designed to operate within a wide temperature range. They can typically function reliably from - 55°C to +125°C. This wide temperature range makes them suitable for use in various environments, including automotive, industrial, and consumer electronics applications where temperature variations can be significant.
## 4. Electrical Performance
### Equivalent Series Resistance (ESR)
The ESR of the ECJ2YF1A475Z is relatively low. A low ESR is beneficial in applications such as power supply filtering, where it helps to reduce power losses and improve the efficiency of the circuit. It also allows the capacitor to handle high - frequency currents more effectively, minimizing voltage ripple in power supplies.
### Dissipation Factor
The dissipation factor of the capacitor is an important parameter that indicates the amount of energy lost as heat during the charging and discharging cycles. The ECJ2YF1A475Z series has a low dissipation factor, which means that it can operate more efficiently and generate less heat, contributing to the overall reliability and longevity of the electronic system.
