MateDescription

• Dielectric Material: The X7R dielectric is employed. X7R is a ceramic - based dielectric renowned for its ability to maintain relatively stable capacitance performance across a wide temperature spectrum. In the temperature range of - 55°C to +125°C, the change in capacitance is within an acceptable range, making it suitable for a diverse range of applications where stability is crucial.
• Electrode Material: Metal electrodes are utilized. These electrodes offer excellent electrical conductivity, which is essential for the efficient transfer of electrical charge in and out of the capacitor. Their stability also contributes to the long - term reliability of the component in different electrical environments.

Features

• Stable Performance: Thanks to the X7R dielectric, the capacitor can function stably under varying temperature conditions. This makes it suitable for use in environments where temperature fluctuations are common, such as in industrial electronics or automotive applications.
• Good Tolerance: With a ±10% capacitance tolerance, it can meet the requirements of most general - purpose electronic circuits. This level of precision ensures that the capacitor can be used in circuits where the exact capacitance value is not overly critical but still needs to be within a reasonable range.
• Low Equivalent Series Resistance (ESR): It exhibits a relatively low ESR, which is beneficial for high - frequency applications. A low ESR allows for efficient filtering and decoupling of high - frequency signals, reducing signal losses and improving the overall performance of the circuit.
• RoHS - Compliant: The product adheres to RoHS standards, meaning it is free from hazardous substances. This makes it an environmentally friendly choice for manufacturers who need to meet strict environmental regulations in their products.

Types

• Capacitor Type: It is a multilayer ceramic capacitor. Multilayer ceramic capacitors are characterized by their high capacitance density, which allows for a relatively large capacitance value to be packed into a small physical size. They also have good frequency response characteristics, making them suitable for a wide range of applications, from power supply filtering to signal coupling.

Applications

• Power Supply Filtering in Consumer Electronics: In devices like smartphones, tablets, and smart TVs, the CL31B225KAHNNNE can be used in power supply circuits to filter out unwanted electrical noise and ripples. By doing so, it helps to provide a stable power supply to the sensitive electronic components within these devices, ensuring their proper operation.
• Decoupling in Circuit Boards: In printed circuit boards (PCBs) containing integrated circuits (ICs), this capacitor can be used for decoupling purposes. Decoupling capacitors are placed near the power pins of ICs to bypass high - frequency noise back to the power source, preventing it from interfering with the normal operation of the IC.
• Automotive Electronics: In automotive applications, such as engine control units (ECUs) and infotainment systems, the capacitor can be used to handle the electrical noise generated by various components in the vehicle. Its ability to operate under a wide temperature range makes it suitable for the harsh automotive environment.

Frequently Ask Questions

• How does temperature affect the capacitance value of the CL31B225KAHNNNE? Due to the X7R dielectric, the capacitance value of this capacitor will change within a certain range as the temperature varies between - 55°C and +125°C. The change is typically within the specified tolerance limits for the X7R dielectric, ensuring that the capacitor can still function effectively in most applications within this temperature range.
• Can the CL31B225KAHNNNE be used in high - voltage applications? No, this capacitor has a rated voltage of 25V. Using it in applications with voltages higher than this rating can cause the capacitor to break down, leading to failure and potentially damaging other components in the circuit.
• What is the expected lifespan of the CL31B225KAHNNNE? The lifespan of the capacitor depends on various factors such as operating temperature, applied voltage, and the electrical and mechanical stress in the circuit.
