Technical Specifications

The CL21A476MQYNYNF boasts a capacitance of 47 microfarads (µF) with a tolerance of ±20%. Its voltage rating is 25 volts. The X5R temperature coefficient ensures that the capacitance remains relatively stable between -55°C and +85°C. The 0805 case size is a standard size for surface-mount components, allowing for easy integration into automated assembly processes. It is designed for reflow soldering. The component is lead-free and RoHS compliant, ensuring environmental friendliness.

This capacitor is commonly used in power rails of digital circuits for decoupling purposes. The large capacitance value helps to smooth out voltage dips and spikes, preventing malfunctions or damage to sensitive components. Its compact size allows it to be placed close to the IC being decoupled, which minimizes the inductance of the connection and maximizes the effectiveness of the decoupling.
