# Introduction to the GRM155R71C153KA01D Product Series
## 1. Overview
The GRM155R71C153KA01D belongs to a high - performance series of multilayer ceramic capacitors (MLCCs). These components are essential building blocks in modern electronic circuits, offering reliable capacitance solutions for a wide range of applications. MLCCs are known for their compact size, high capacitance values, and excellent electrical characteristics, and the GRM155R71C153KA01D series is no exception.
## 2. Product Naming Convention
Let's break down the product code "GRM155R71C153KA01D" to understand its key features:
- **GRM**: This is the product series prefix, which is specific to the manufacturer's naming system and indicates the general family of MLCCs.
- **155**: It represents the size of the capacitor. In this case, it typically refers to a 0603 (inches) or 1608 (metric) package size. The 0603 size is widely used due to its relatively small footprint, making it suitable for applications where space is at a premium.
- **R7**: This indicates the dielectric type. The R7 dielectric is a Class II dielectric, which offers a relatively high capacitance per unit volume. It has a temperature coefficient of ±15% over a temperature range of - 55°C to +125°C, making it suitable for a variety of operating environments.
- **1C**: The "1" represents the voltage rating. In this series, it corresponds to a rated voltage of 16V. The "C" is part of the code related to the capacitance tolerance and other characteristics.
- **153**: This is the capacitance value code. Using the standard three - digit code system, the first two digits (15) are the significant figures, and the third digit (3) is the multiplier. So, 153 means \(15\times10^{3}\) pF, which is equivalent to 15 nF.
- **KA**: It indicates the capacitance tolerance. The "KA" code represents a tolerance of ±10%.
- **01D**: This is a manufacturer - specific code that may include information about the production lot, packaging, or other details specific to the manufacturing process.
## 3. Electrical Characteristics
### Capacitance
With a nominal capacitance of 15 nF and a tolerance of ±10%, the GRM155R71C153KA01D provides a reliable and consistent capacitance value within the specified range. This makes it suitable for applications where precise capacitance values are required, such as in filtering circuits, coupling circuits, and timing circuits.
### Voltage Rating
The rated voltage of 16V means that the capacitor can safely operate at voltages up to 16V without significant degradation of its performance or risk of breakdown. This voltage rating makes it suitable for a wide range of low - voltage electronic circuits, including those found in consumer electronics, mobile devices, and small - scale industrial control systems.
### Temperature Coefficient
As mentioned earlier, the R7 dielectric has a temperature coefficient of ±15% over the temperature range of - 55°C to +125°C. This means that the capacitance value of the capacitor will change by a maximum of ±15% within this temperature range. While this is a relatively large change compared to some Class I dielectrics, it is still acceptable for many applications where temperature stability is not the most critical factor.
