Surface Mount Multilayer Ceramic Chip Capacitors (SMD MLCCs) COG Dielectric, 10-250 VDC (Commercial Grade)

Category: Capacitors, Electronics, Kemet Electronics Corporation

Overview

KEMET’s Surface Mount Multilayer Ceramic Chip Capacitors (MLCCs) with COG dielectric are designed for commercial applications requiring high stability and reliability. These capacitors are classified as Class I temperature compensating components, ideal for resonant circuits and applications where consistent capacitance is crucial. The COG dielectric ensures a stable capacitance that is unaffected by time or voltage and experiences minimal change with temperature fluctuations, with the change limited to +30 ppm/°C across a wide temperature range from -55°C to +125°C.

Benefits

The capacitors offer a broad operating temperature range of -55°C to +125°C. They are also Lead (Pb)-free, conforming to RoHS and REACH environmental directives. Available in various case sizes from EIA 0201 to 2225 and voltage ratings ranging from 10V to 250V. The capacitance values extend from 0.5 pF to 0.47 µF, with multiple tolerance options including ±0.10 pF up to ±20%. The components are known for their lack of piezoelectric noise, extremely low Equivalent Series Resistance (ESR) and Inductance (ESL), high thermal stability, and capability to handle high ripple currents.

Ordering Information

This section guides the ordering process, illustrating how to specify desired capacitors. KEMET provides a systematic approach to selecting the rated case size, capacitance value, tolerance, voltage, failure rate, termination finish, packaging, and whether a flexible termination option is needed. A variety of capacitance tolerance ranges are offered, from very precise (±0.10 pF) to more general (±20%). The ordering information includes a detailed explanation of the significance of each digit and letter in the part numbering system. For example, a capacitor with a value of 2.2 pF in a 1206 case would have the code ‘229’, while 0.5 pF would be ‘508’.

The datasheet notes the availability of additional tolerance and termination finish options, advising customers to contact KEMET for further information. The company’s commitment to providing a wide range of options is evident in the flexibility and customization available to customers. KEMET’s contact information and headquarters in Greenville, South Carolina are also provided, alongside the issue date of the datasheet.
