series introduction
# Introduction to the GRM188R61A474KA61D Product Series
## 1. Overview
The GRM188R61A474KA61D belongs to a highly specialized and widely - used product series, typically within the realm of electronic components. This series is often associated with multilayer ceramic capacitors (MLCCs), which are fundamental building blocks in modern electronic circuits. These capacitors play a crucial role in various applications, from consumer electronics to industrial equipment, due to their excellent electrical properties and reliability.
## 2. Product Specifications
### Physical Characteristics
- **Size**: The "188" in the model number usually indicates the physical dimensions of the capacitor. In the case of MLCCs, it follows a specific industry - standard size code. This particular size is relatively compact, making it suitable for applications where space is at a premium, such as in mobile devices, wearables, and small - form - factor circuit boards.
- **Case Style**: It likely has a surface - mount technology (SMT) case style. SMT components are designed to be directly mounted onto the surface of a printed circuit board (PCB), which simplifies the manufacturing process and allows for high - density circuit designs.
### Electrical Characteristics
#### Capacitance
- The "474" in the model number represents the capacitance value. Using the standard capacitor code system, 474 means \(47\times10^{4}\) picofarads (pF). So, the capacitance of the GRM188R61A474KA61D is \(470000\) pF or \(0.47\) microfarads (\(\mu F\)). This capacitance value is suitable for a wide range of filtering, coupling, and decoupling applications in electronic circuits.
#### Voltage Rating
- The "1A" in the model number typically indicates the voltage rating. In the capacitor coding system, "1A" corresponds to a voltage rating of 10V. This means that the capacitor can safely operate at a maximum DC voltage of 10 volts. It is important to ensure that the voltage across the capacitor in the circuit does not exceed this rating to prevent damage to the component.
#### Dielectric Material
- The "R6" indicates the type of dielectric material used in the capacitor. In this case, it is a Class II dielectric, specifically an X5R dielectric. X5R dielectrics offer a good balance between capacitance stability and temperature performance. They have a relatively high capacitance per unit volume and can operate over a temperature range of - 55°C to + 85°C with a capacitance change of ±15%.
#### Tolerance
- The "K" in the model number represents the capacitance tolerance. A "K" tolerance means that the actual capacitance value of the capacitor can deviate from the nominal value by ±10%. This level of tolerance is acceptable for many general - purpose applications, but for more precise circuits, components with tighter tolerances may be required.
## 3. Performance Advantages
### High Capacitance Density
Thanks to the multilayer ceramic construction, the GRM188R61A474KA61D can achieve a relatively high capacitance value in a small physical size. This high capacitance density allows designers to save space on the PCB and reduce the overall size of the electronic device.
### Good Temperature Stability
The X5R dielectric material provides stable capacitance performance over a wide temperature range. This is crucial in applications where the operating temperature may vary, such as in automotive electronics, outdoor - use devices, and industrial control systems. The stable capacitance ensures consistent circuit performance regardless of temperature fluctuations.
