series introduction
# Introduction to the C3225X5R1C156M250AA Product Series
## 1. Overview
The C3225X5R1C156M250AA 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 contains a wealth of information about the capacitor's characteristics and specifications.
## 2. Physical Dimensions
The "C3225" in the model number indicates the physical size of the capacitor. In the industry - standard metric size system, this corresponds to a length of 3.2 mm and a width of 2.5 mm. This relatively compact size makes the C3225X5R1C156M250AA suitable for use in densely packed printed circuit boards (PCBs), where space is often at a premium. It allows for high - density component placement, enabling the design of smaller and more portable electronic devices.
## 3. Dielectric Material
The "X5R" represents the dielectric material used in the capacitor. X5R is a Class II dielectric, which offers a good balance between capacitance, temperature stability, and cost.
- **Temperature Range**: It can operate within a temperature range of - 55°C to + 85°C. This wide temperature tolerance makes the capacitor suitable for use in a variety of environments, from industrial settings with high - temperature variations to consumer electronics that may be exposed to different ambient temperatures.
- **Capacitance Stability**: The capacitance of an X5R capacitor changes by no more than ±15% over its specified temperature range. This stability ensures that the capacitor can maintain its electrical performance under different temperature conditions, which is crucial for the proper functioning of electronic circuits.
## 4. Capacitance Value
The "156" in the model number is used to denote the capacitance value. In the capacitor coding system, the first two digits are significant figures, and the third digit is the multiplier. So, for "156", the capacitance value is calculated as 15 × 10⁶ picofarads (pF), which is equivalent to 15 microfarads (μF). This relatively high capacitance value makes the C3225X5R1C156M250AA suitable for applications that require large - scale energy storage, such as power supply filtering and decoupling.
## 5. Tolerance
The "M" indicates the capacitance tolerance of the capacitor. An "M" tolerance means that the actual capacitance value of the capacitor can deviate from the nominal value 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. For applications that require more accurate capacitance, other capacitors with tighter tolerances may be used.
## 6. Voltage Rating
The "250" represents the rated voltage of the capacitor, which is 250 volts (V). This means that the capacitor can safely operate at voltages up to 250 V without the risk of dielectric breakdown. The voltage rating is an important parameter, as exceeding the rated voltage can lead to permanent damage to the capacitor and potentially cause malfunctions in the electronic circuit. It is suitable for use in medium - voltage applications, such as some power supplies and motor control circuits.
## 7. Packaging and Termination
The "AA" at the end of the model number typically refers to the packaging and termination details of the capacitor. The specific meaning may vary depending on the manufacturer, but generally, it provides information about the type of termination (e.g., plated terminations
