The datasheet provides comprehensive information on KEMET’s line of Surface Mount Multilayer Ceramic Chip Capacitors (SMD MLCCs) with COG dielectric, tailored for commercial-grade applications. These capacitors are designed for a wide range of DC voltage ratings from 10VDC to 200VDC and have a notable endurance for operating temperatures ranging from -55°C to +125°C. COG dielectric components are known for their stable capacitance over temperature fluctuations, making them ideal for resonant circuit applications or where consistency and quality of capacitance are crucial.
Benefits outlined include negligible capacitance fluctuation with temperature changes, absence of capacitance decay over time, non-polarity for easy installation, pure matte or SnPb plated tin terminations for improved solderability, and a broad variety of capacitance offerings from 0.5pF up to 0.47uF. These capacitors are also RoHS compliant, highlight low equivalent series resistance (ESR) and equivalent series inductance (ESL), and are immune to piezoelectric noise, with additional features making them suitable for critical timing and tuning among other applications.
Applications for KEMET’s SMD MLCCs are diverse, covering essential timing and tuning circuits, high current pulse circuits, decoupling, bypass and filtering functions, transient voltage suppression, blocking, and energy storage. They are presented as the preferred capacitance solution for frequency demands at line frequencies and into the MHz range.
Ordering Information
The ordering information section breaks down how to select the correct SMD MLCC based on case size, capacitance, tolerance, and voltage rating. The part number is constructed from a systematic approach involving the case size followed by important specifications such as the series code, capacitance value coded with significant digits and number of zeros, capacitance tolerance, and the designator for voltage rating. The datasheet also indicates availability of different termination finishes and packaging options upon request.
Physical Dimensions and Mounting Technique
Detailed physical dimensions of the capacitors are provided in both millimeters and inches, specifying the length, width, thickness, and minimum separation of electrode bands according to the EIA metric code. The capacitors require either solder reflow or solder wave reflow for mounting, depending on their size. There is also mention of commercial-grade products undergoing internal qualification with details in a referenced table.
For environmental compliance, all products in this range are RoHS compliant, ensuring adherence to regulations restricting the use of certain hazardous substances in electronic equipment.
