series introduction
# Introduction to the GRM188R61A225KE34D Product Series
## 1. Overview
The GRM188R61A225KE34D belongs to a highly specialized and widely - used product series in the field of electronic components. This series is primarily known for its application as multilayer ceramic capacitors (MLCCs), which are essential building blocks in modern electronic circuits. These capacitors play a crucial role in various electronic devices, from consumer electronics to industrial equipment, by storing and releasing electrical energy as needed.
## 2. Product Specifications
### Physical Dimensions
The GRM188 series is designed with a compact form factor. The "188" in the model number typically indicates the size of the capacitor. In this case, it has a standardized physical dimension that allows for easy integration into printed circuit boards (PCBs). The small size makes it suitable for applications where space is at a premium, such as in mobile phones, tablets, and wearable devices.
### Capacitance
The "225" in the model number represents the capacitance value of the capacitor. Using the common capacitor value coding system, 225 translates to a capacitance of 2.2 μF (microfarads). This capacitance value is significant as it determines the amount of electrical charge the capacitor can store. A 2.2 μF capacitor can hold a relatively large amount of charge compared to smaller - value capacitors, making it useful in applications that require energy storage for filtering, coupling, or decoupling purposes.
### Voltage Rating
The "1A" in the model number indicates the voltage rating of the capacitor. In this case, it has a rated voltage of 10V. This means that the capacitor can safely operate in circuits where the voltage across its terminals does not exceed 10 volts. It is important to select a capacitor with an appropriate voltage rating to ensure its reliable operation and prevent damage due to over - voltage conditions.
### Dielectric Material
The "R6" in the model number refers to the dielectric material used in the capacitor. The R6 dielectric is a type of ceramic dielectric that offers a good balance between capacitance, temperature stability, and cost. It has a relatively high dielectric constant, which allows for the construction of capacitors with high capacitance values in a small physical size. However, the capacitance of R6 dielectric capacitors may vary with temperature, typically within a certain tolerance range.
### Tolerance
The "KE" in the model number indicates the capacitance tolerance of the capacitor. A "KE" tolerance means that the actual capacitance value of the capacitor can deviate from the nominal value (2.2 μF in this case) by ±10%. This tolerance is an important consideration in applications where precise capacitance values are required, such as in some analog circuits or frequency - sensitive applications.
### Packaging
The "34D" in the model number may refer to the packaging type and other specific characteristics of the capacitor. It is likely a surface - mount device (SMD) package, which is the most common type of packaging for modern MLCCs. SMD packages are designed for automated assembly processes, allowing for high - volume production of electronic circuits.
## 3. Key Features
### High Capacitance in a Small Size
One of the main advantages of the GRM188R61A225KE34D series is its ability to provide a relatively high capacitance value (2.2 μF) in a compact physical package. This is achieved through advanced manufacturing techniques and the use of high - dielectric - constant ceramic materials. The small size makes it ideal for miniaturized electronic devices, where space is a critical factor.
### Good Frequency Response
These capacitors have a good frequency response, which means they can effectively store and release electrical energy at different frequencies.
