series introduction
# Introduction to the C1005X5R0J475K050BC Product Series
## 1. Overview
The C1005X5R0J475K050BC product series belongs to the category of multilayer ceramic capacitors (MLCCs). These capacitors are essential passive electronic components widely used in various electronic circuits for functions such as energy storage, filtering, coupling, and decoupling. Their compact size and high performance make them a popular choice in modern electronic devices.
## 2. Product Naming Convention
Let's break down the product code "C1005X5R0J475K050BC" to understand its key specifications:
- **C**: Usually indicates that it is a capacitor.
- **1005**: This represents the physical size of the capacitor, also known as the chip size. In the metric system, 1005 corresponds to a length of 1.0 mm and a width of 0.5 mm. This small size makes it suitable for applications where space is limited, such as in mobile devices and wearable electronics.
- **X5R**: It is the dielectric type of the capacitor. X5R is a Class II dielectric, which offers a good balance between capacitance, temperature stability, and cost. It has a temperature range of -55°C to +85°C, and the capacitance change within this temperature range is typically within ±15%.
- **0J**: The "0" is often a placeholder or part of the internal coding of the manufacturer. The "J" represents the voltage rating. In this case, "J" typically corresponds to a voltage rating of 6.3 V.
- **475**: This is the capacitance value code. The first two digits (47) are the significant figures, and the third digit (5) is the multiplier. So, the capacitance value is calculated as 47 × 10⁵ pF, which is equal to 4.7 μF.
- **K**: It indicates the tolerance of the capacitance. "K" means a tolerance of ±10%. This means that the actual capacitance of the capacitor can vary within ±10% of the nominal value (4.7 μF in this case).
- **050**: This may be a part of the manufacturer - specific internal coding, which could be related to production batch, process version, or other non - standard specifications.
- **BC**: Similar to "050", "BC" is likely a manufacturer - specific code for additional product features, packaging options, or quality grades.
## 3. Electrical Characteristics
### Capacitance
With a nominal capacitance of 4.7 μF, the C1005X5R0J475K050BC capacitors can store a relatively large amount of electrical charge for their small size. This makes them suitable for applications where a certain amount of energy needs to be stored or where a stable voltage supply is required.
### Voltage Rating
The 6.3 V voltage rating means that the capacitor can safely operate in circuits where the maximum voltage across it does not exceed 6.3 V. Exceeding this voltage can lead to dielectric breakdown, which may damage the capacitor and affect the performance of the entire circuit.
### Temperature Stability
Thanks to the X5R dielectric, the capacitance of these capacitors remains relatively stable within the temperature range of -55°C to +85°C. This makes them suitable for use in environments with moderate temperature variations, such as in consumer electronics, automotive electronics (for non - critical under - hood applications), and industrial control systems.
### Tolerance
The ±10% tolerance ensures that the actual capacitance of the capacitor will be within an
