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 (SMD MLCCs) with COG dielectric are designed for commercial applications requiring stable capacitor performance. These capacitors sport a high maximum operating temperature of 125°C and are defined by the Electronics Components, Assemblies & Materials Association (EIA) as Class I materials, which means they are temperature compensating, making them ideal for resonant circuit applications or for use where Quality factor (Q) and stability of capacitance characteristics are crucial.

One of the key features of the COG dielectric is that it shows no change in capacitance with respect to time and voltage. It also demonstrates a minimal change in capacitance in response to ambient temperature variations, with capacitance change constrained to +30 ppm/°C within a wide temperature range of -55°C to +125°C.

Benefits

These MLCCs by KEMET offer a series of benefits due to their characteristic properties. They operate within a wide temperature range and are compliant with Lead (Pb)-free, RoHS, and REACH standards. Their case sizes are versatile, ranging from EIA 0201 to 2225. They can handle DC voltage ratings from 10V up to an impressive 250V and offer capacitance values between 0.5 pF and 0.47 µF.

The capacitors come with a variety of capacitance tolerances, such as +0.10 pF, +0.25 pF, +0.5 pF, +1%, +2%, +5%, +10%, and ±20%, to meet different precision requirements. Users can expect no piezoelectric noise from these capacitors, which also have extremely low Equivalent Series Resistance (ESR) and Equivalent Series Inductance (ESL), high thermal stability, and high ripple current capability, ensuring reliable performance in a variety of applications.

Ordering Information

To place an order for KEMET’s Surface Mount MLCCs, one can reference the detailed ordering information provided in the datasheet. This includes case sizes denoted by EIA standards, series codes, capacitance values that follow a unique digit-zero system, capacitance tolerances, and failure rate, along with termination design and packaging options. For instance, a capacitance value of 2.2 pF would be coded as 229, while 0.5 pF would be represented as 508. Termination finish is identified by a special code, and the available packaging and ceramic grade options are indicated within the datasheet.

There is also an opportunity to choose capacitors with a flexible termination option, with further details available in the FT-CAP product bulletin. Customers are encouraged to reach out to KEMET for additional capacitance tolerance offerings or termination finish options that might suit their specific application needs.
