series introduction
# Introduction to the GRM155R61A105KE15 Product Series
## 1. Overview
The GRM155R61A105KE15 belongs to a high - performance capacitor product series, which is widely used in various electronic circuits due to its excellent electrical properties and reliable performance. These capacitors are designed to meet the demanding requirements of modern electronic devices, providing stable capacitance and low equivalent series resistance (ESR) for efficient operation.
## 2. Product Specifications
### Physical Characteristics
- **Size**: The GRM155 series typically features a compact size, which is crucial for applications where space is limited. The specific dimensions of the GRM155R61A105KE15 are carefully engineered to fit into densely populated printed circuit boards (PCBs). This compactness allows for more efficient use of board space, enabling the design of smaller and more portable electronic devices.
- **Case Style**: It comes in a surface - mount device (SMD) package. SMD technology offers several advantages, such as easier automated assembly, better mechanical stability on the PCB, and improved electrical performance due to shorter lead lengths, which reduce parasitic inductance.
### Electrical Characteristics
#### Capacitance
- The capacitor has a capacitance value of 1 μF (since 105 represents \(10\times10^{5}\) pF = 1 μF). This capacitance value is suitable for a wide range of applications, including decoupling, filtering, and energy storage in electronic circuits. Decoupling capacitors are used to provide a local reservoir of charge to stabilize the power supply voltage, while filtering capacitors are used to remove unwanted noise and ripple from the power supply or signal lines.
#### Voltage Rating
- It has a rated voltage of 10 V (the '1A' in the part number indicates a voltage rating of 10 V according to the standard capacitor coding system). This voltage rating determines the maximum voltage that the capacitor can safely withstand without experiencing breakdown or other electrical failures. It is important to select a capacitor with an appropriate voltage rating for the specific application to ensure reliable operation.
#### Tolerance
- The capacitor has a capacitance tolerance of ±10% (indicated by the 'K' in the part number). This tolerance specifies the allowable deviation from the nominal capacitance value. A ±10% tolerance means that the actual capacitance of the capacitor can vary between 0.9 μF and 1.1 μF. In most applications, this level of tolerance is acceptable, but in some precision circuits, a tighter tolerance may be required.
#### Dielectric Type
- The 'R6' in the part number indicates that it uses a Class II dielectric material. Class II dielectrics, such as X7R, offer relatively high capacitance values in a small package size. They also have a moderate temperature coefficient of capacitance, which means that the capacitance value changes within a certain range as the temperature varies. This makes them suitable for a wide range of operating temperatures, typically from - 55°C to +125°C.
#### Equivalent Series Resistance (ESR)
- The GRM155R61A105KE15 has a relatively low ESR. Low ESR is beneficial in applications where high - frequency performance is required, such as in switching power supplies. A low ESR capacitor can handle high - frequency currents more efficiently, reducing power losses and heat generation in the circuit.
## 3. Applications
### Power Supply Circuits
- In power supply circuits, the GRM155R61A105KE15 can be used as a decoupling capacitor. It helps to reduce voltage fluctuations and noise on the power lines by providing a local source of charge. This is especially important in digital
