series introduction
# Introduction to the C1005X5R0J475M Product Series
## 1. Overview
The C1005X5R0J475M product series belongs to the category of multilayer ceramic capacitors (MLCCs). These capacitors are essential passive electronic components widely used in various electronic circuits to store and release electrical energy, filter signals, and stabilize voltage levels. The specific model designation "C1005X5R0J475M" contains a wealth of information about the capacitor's characteristics and specifications.
## 2. Physical Dimensions
The "1005" in the model number refers to the capacitor's size in the metric system. In this case, it has a length of 1.0 mm and a width of 0.5 mm. This compact size makes the C1005X5R0J475M series suitable for applications where space is limited, such as in mobile devices, wearable electronics, and other miniaturized electronic products. The small form - factor allows for high - density circuit board designs, enabling manufacturers to pack more functionality into a smaller space.
## 3. Dielectric Material
The "X5R" indicates the type of dielectric material used in the capacitor. X5R is a Class II dielectric, which offers a good balance between capacitance value, temperature stability, and cost. It has a relatively high dielectric constant, which allows for the production of capacitors with relatively large capacitance values in a small physical size.
### Temperature Characteristics
The "X" in X5R means that the capacitor can operate in a temperature range from - 55°C to + 85°C. The capacitance change over this temperature range is within ±15%. This makes the C1005X5R0J475M series suitable for applications where the operating temperature may vary, such as in automotive electronics, industrial control systems, and consumer electronics that are exposed to different environmental conditions.
## 4. Voltage Rating
The "0J" in the model number represents the voltage rating of the capacitor. In this case, the voltage rating is 6.3 V. This means that the capacitor can safely operate at a maximum DC voltage of 6.3 V. It is crucial to select a capacitor with an appropriate voltage rating for a given application to ensure reliable operation and prevent capacitor failure due to over - voltage conditions.
## 5. Capacitance Value
The "475" in the model number is used to denote the capacitance value. The first two digits (47) are the significant figures, and the third digit (5) is the multiplier. Using the standard capacitor value coding system, the capacitance value is calculated as 47 × 10⁵ pF, which is equal to 4.7 μF. This relatively large capacitance value for a small - sized capacitor makes the C1005X5R0J475M series useful for applications that require energy storage, such as power supply filtering and decoupling.
## 6. Tolerance
The "M" at the end of the model number indicates the capacitance tolerance. An "M" tolerance means that the actual capacitance value of the capacitor can deviate from the nominal value (4.7 μF in this case) by ±20%. While this may seem like a relatively large tolerance, it is acceptable for many general - purpose applications where precise capacitance values are not critical.
## 7. Applications
### Power Supply Filtering
In power supply circuits, the C1005X5R0J475M capacitors can be used to filter out high - frequency noise and ripple from the DC power supply. They store electrical energy during the peaks of the power supply voltage and release it during the troughs, helping
