series introduction
# Introduction to the GRM188R72A104KA35D Product Series
## 1. Overview
The GRM188R72A104KA35D belongs to a high - performance series of multilayer ceramic capacitors (MLCCs). These capacitors are essential passive components widely used in various electronic circuits, playing a crucial role in functions such as filtering, decoupling, and energy storage.
## 2. Product Specifications
### Physical Characteristics
- **Size**: The "188" in the model number indicates the size of the capacitor. It follows a standard industry - defined dimension, which is typically 1.6mm x 0.8mm x 0.8mm (length x width x height). This compact size makes it suitable for use in densely populated printed circuit boards (PCBs), especially in applications where space is at a premium, such as mobile devices, wearables, and small - form - factor consumer electronics.
- **Termination**: The capacitor is equipped with high - quality terminations that ensure good electrical contact and mechanical stability on the PCB. These terminations are designed to withstand the soldering process and provide reliable performance over the product's lifespan.
### Electrical Characteristics
#### Capacitance
- The "104" in the model number represents the capacitance value. Using the standard capacitor code system, 104 means \(10\times10^{4}\) picofarads (pF), which is equivalent to 0.1 microfarads (\(\mu F\)). This capacitance value is commonly used in a wide range of applications, from power supply filtering to signal coupling in audio and radio frequency (RF) circuits.
#### Dielectric Type
- The "R7" indicates the dielectric type. R7 is a Class II dielectric, specifically a X7R dielectric. X7R dielectrics are known for their relatively high capacitance per unit volume and good temperature stability. They can operate over a wide temperature range from - 55°C to +125°C, with a capacitance change of ±15% within this temperature range. This makes the GRM188R72A104KA35D suitable for use in environments where temperature variations are significant.
#### Voltage Rating
- The "2A" represents the voltage rating. In the capacitor code system, 2A corresponds to a rated voltage of 100V. This means that the capacitor can safely operate at a maximum DC voltage of 100V. It is important to select a capacitor with an appropriate voltage rating to ensure the reliability and safety of the circuit.
#### Tolerance
- The "K" indicates the capacitance tolerance. A "K" tolerance means that the actual capacitance value of the capacitor can deviate from the nominal value (0.1\(\mu F\)) by ±10%. This level of tolerance is acceptable for many general - purpose applications, but for more precise circuits, such as precision oscillators or high - end audio equipment, a capacitor with a tighter tolerance may be required.
#### DC Bias Characteristics
- The capacitor has specific DC bias characteristics. As the DC voltage applied across the capacitor increases, the capacitance value may decrease. The GRM188R72A104KA35D is designed to have relatively stable capacitance under DC bias conditions, ensuring consistent performance in circuits where a DC voltage is present, such as power supply filtering circuits.
## 3. Applications
### Power Supply Filtering
- In power supply circuits, the GRM188R72A104KA35D can be used as a decoupling capacitor. It helps to reduce the noise and ripple in the power supply by providing a low - impedance path for high - frequency currents. By placing these capacitors close
