Additional Details

This MLCC is typically available in various voltage ratings. The specific capacitance value (4.7uF), tolerance, and voltage rating are crucial parameters to consider when selecting the capacitor for a specific application. Refer to the Kemet datasheet for detailed specifications, including temperature coefficient, dissipation factor, and insulation resistance. The datasheet will also outline recommended soldering profiles for optimal assembly and performance. It is critical to adhere to the recommended soldering profiles to prevent damage to the component during the soldering process. The capacitor’s case size can be determined using EIA (Electronic Industries Alliance) standards.

X7R dielectrics are characterized by predictable change in capacitance with respect to time, voltage, and ambient temperature. Capacitance change is limited to ±15% from -55°C to +125°C. This particular capacitor is generally used in applications where a specific capacitance value is not critical, but the stability of the capacitance over a wide range of temperatures is important. Examples include decoupling, bypass, filtering and transient voltage suppression in commercial, industrial and automotive applications.

Proper storage is important to maintain solderability. Consult the manufacturer's recommendations for specific storage guidelines, particularly regarding temperature and humidity control. Also, always check the manufacturer's datasheet for specific application notes and considerations related to this component.
