series introduction
# Introduction to the GRM155R61H104KE19D Product Series
## 1. Overview
The GRM155R61H104KE19D belongs to a high - performance capacitor product series. Capacitors are fundamental passive electronic components that play a crucial role in a wide range of electronic circuits, and this particular series is designed to meet the demanding requirements of modern electronic applications.
## 2. Product Specifications
### Physical Dimensions
- The GRM155 series typically features a compact size, which is highly beneficial for applications where space is at a premium. The "155" in the model number often indicates a specific size code, usually corresponding to a small form - factor that allows for high - density PCB (Printed Circuit Board) layouts. This makes it suitable for use in portable electronic devices such as smartphones, tablets, and wearables.
### Capacitance
- The "104" in the model number represents the capacitance value. Using the standard capacitor coding system, 104 means \(10\times10^{4}\) picofarads (pF), which is equivalent to 0.1 microfarads (\(\mu F\)). This capacitance value is commonly used in various filtering, coupling, and decoupling applications in electronic circuits.
### Dielectric Material
- The "R6" indicates the type of dielectric material used. In this case, it is a Class II dielectric. Class II dielectrics offer relatively high capacitance values in a small package size. They have a non - linear capacitance - temperature characteristic, which means the capacitance value can change with temperature. However, they are still suitable for many general - purpose applications where cost - effectiveness and high capacitance per unit volume are important.
### Voltage Rating
- The "1H" represents the voltage rating. In the capacitor coding system, "1H" corresponds to a voltage rating of 50V. This means the capacitor can safely operate in circuits where the voltage across it does not exceed 50 volts. It is important to select a capacitor with an appropriate voltage rating to ensure reliable operation and prevent damage to the component.
### Tolerance
- The "KE" indicates the capacitance tolerance. A "KE" tolerance typically means ±10%. This means that the actual capacitance value of the capacitor can vary within ±10% of the nominal value (0.1\(\mu F\) in this case). For applications where precise capacitance values are not critical, a ±10% tolerance is often acceptable.
### Temperature Coefficient
- Although not explicitly detailed in the model number, the capacitor's temperature coefficient is an important characteristic. Class II dielectrics like the one used in this series usually have a relatively large temperature coefficient, which means the capacitance can change significantly with temperature. However, the manufacturer has designed the product to operate within a specified temperature range, typically from - 55°C to +125°C, ensuring reliable performance in a wide variety of environmental conditions.
## 3. Applications
### Power Supply Filtering
- In power supply circuits, the GRM155R61H104KE19D can be used as a decoupling capacitor. It helps to smooth out the voltage fluctuations and reduce noise in the power supply lines. By providing a low - impedance path for high - frequency noise, it ensures that the electronic components in the circuit receive a stable and clean power supply. This is particularly important in sensitive electronic devices such as microcontrollers, where power supply noise can cause malfunctions.
### Signal Coupling
- In audio and radio frequency (RF) circuits, the capacitor can be used for signal coupling. It allows the AC component of a signal to pass through while blocking the DC component. This is essential for transferring signals between different stages
