# Introduction to the GRM1555C1H470JZ01D Product Series
## 1. Overview
The GRM1555C1H470JZ01D belongs to a high - performance product series of multilayer ceramic capacitors (MLCCs). These capacitors are essential components in modern electronic circuits, playing a crucial role in various applications due to their unique electrical properties and reliable performance.
## 2. Product Naming Convention
Let's break down the product code "GRM1555C1H470JZ01D" to understand its key features:
- **GRM**: This is the product series prefix, which is a well - recognized identifier for the manufacturer's specific line of MLCCs, indicating a certain level of quality and design standard associated with the brand.
- **155**: It typically represents the size code of the capacitor. In this case, it corresponds to a specific physical dimension, which is important for PCB (Printed Circuit Board) layout and component placement.
- **5C**: This part of the code may be related to the dielectric material and its characteristics. Different dielectric materials offer different performance parameters such as capacitance stability, temperature coefficient, and voltage rating.
- **1H**: Usually, this indicates the rated voltage of the capacitor. The specific voltage value associated with "1H" is defined by the manufacturer's coding system.
- **470**: This represents the capacitance value. In the standard capacitor coding system, "470" means a capacitance of 47 pF (picofarads). The first two digits (47) are the significant figures, and the third digit (0) indicates the number of zeros to be added after the significant figures.
- **J**: It is the tolerance code. A "J" tolerance means that the actual capacitance value of the capacitor can deviate by ±5% from the nominal value of 47 pF.
- **Z01D**: This is likely a specific suffix code that may include additional information such as packaging type, manufacturing process details, or special features unique to this particular product within the series.
## 3. Electrical Characteristics
### Capacitance
The nominal capacitance of the GRM1555C1H470JZ01D is 47 pF with a tolerance of ±5%. This precise capacitance value makes it suitable for applications where accurate capacitance is required, such as in high - frequency circuits and timing circuits.
### Voltage Rating
As indicated by the "1H" in the product code, the capacitor has a specific rated voltage. This voltage rating determines the maximum voltage that the capacitor can safely withstand without experiencing breakdown or significant degradation in performance. It is crucial to ensure that the operating voltage in the circuit does not exceed this rated value to avoid capacitor failure.
### Temperature Coefficient
The dielectric material used in the GRM1555C1H470JZ01D has a specific temperature coefficient. This coefficient describes how the capacitance of the capacitor changes with temperature. A stable temperature coefficient is important in applications where the operating temperature may vary, such as in automotive electronics or industrial control systems.
### Equivalent Series Resistance (ESR)
The ESR of the capacitor is an important parameter, especially in high - frequency applications. A low ESR value indicates that the capacitor can charge and discharge quickly, reducing power losses and improving the efficiency of the circuit. The GRM1555C1H470JZ01D is designed to have a relatively low ESR, making it suitable for high - speed and high - frequency circuits.
