series introduction
# Introduction to the C1005X5R0J106M Product Series
## 1. Overview
The C1005X5R0J106M product series belongs to the category of multilayer ceramic capacitors (MLCCs). These capacitors are essential passive components widely used in various electronic circuits due to their excellent electrical properties, compact size, and high reliability.
## 2. Product Naming Convention
Let's break down the product code “C1005X5R0J106M” to understand its key specifications:
- **C**: Usually indicates that it is a capacitor.
- **1005**: This represents the physical size of the capacitor. In the metric system, 1005 corresponds to a length of 1.0 mm and a width of 0.5 mm. This small form - factor makes it suitable for applications where space is limited, such as in mobile devices, wearables, and other miniaturized electronic products.
- **X5R**: It is the dielectric type. X5R is a Class II dielectric, which offers a good balance between capacitance, temperature stability, and cost. The “X” indicates that the lower temperature limit of the capacitor is - 55°C, and the “5” means the upper temperature limit is +85°C. 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 tolerance of the capacitance value. A “J” tolerance means ±5%, indicating that the actual capacitance of the capacitor can vary by up to 5% from the nominal value.
- **106**: This is the capacitance value code. Using the standard capacitor value coding system, the first two digits (10) are the significant figures, and the third digit (6) is the multiplier. So, the nominal capacitance value is \(10\times10^{6}\) pF, which is equivalent to 10 μF.
- **M**: It represents the voltage rating. In this case, “M” typically corresponds to a voltage rating of 25V.
## 3. Electrical Characteristics
### Capacitance
With a nominal capacitance of 10 μF and a tolerance of ±5%, the actual capacitance of the C1005X5R0J106M capacitor will be in the range of 9.5 μF to 10.5 μF. This relatively high capacitance value makes it suitable for applications that require energy storage, filtering, and decoupling.
### Temperature Stability
Thanks to the X5R dielectric, the capacitor maintains its capacitance within ±15% over the temperature range of - 55°C to +85°C. This temperature stability ensures consistent performance in different environmental conditions, which is crucial for applications in automotive electronics, industrial control systems, and outdoor - used devices.
### Equivalent Series Resistance (ESR)
The ESR of the C1005X5R0J106M is relatively low. A low ESR is beneficial in applications such as power supply filtering, where it helps to reduce power losses and improve the efficiency of the circuit. It also allows the capacitor to handle high - frequency signals effectively, minimizing the ripple voltage in power supplies.
### Dielectric Strength
The capacitor has a voltage rating of 25V, which means it can safely operate at voltages up to 25V without experiencing dielectric breakdown. This voltage rating should be carefully considered when selecting the capacitor for a particular application to ensure reliable operation.
## 4. Applications
### Power Supply Decoupling
In electronic circuits, power supplies often have fluctuations and noise.
