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

Category: Capacitors, Electronics, Kemet Electronics Corporation

Overview

KEMET Electronics Corporation introduces its commercial grade Surface Mount Multilayer Ceramic Chip Capacitors (SMD MLCCs) with COG Dielectric, which support a voltage range from 10V to 250V. These capacitors are highlighted for their stability across temperatures from -55°C to +125°C, making them suitable for circuits that require consistent capacitance. They are compliant with the EIA’s Class I material standards, implying reliable temperature compensation ideal for resonant circuit applications.

Benefits

The SMD MLCCs are characterized by a number of key benefits:

Lead (Pb)-free, conforming to RoHS and REACH directives.
Available in a wide range of case sizes, including EIA 0201 through 2225.
Diverse capacitive options from 0.5pF to 0.47pF and variable tolerance levels ranging from ±0.10pF to ±20%.
Excellent thermal stability, low Equivalent Series Resistance (ESR), and Equivalent Series Inductance (ESL).
Resistance to piezoelectric noise and high ripple current capability.

Additionally, the COG dielectric capacitors do not suffer from capacitance changes over time or when exposed to applied rated DC voltage, making them highly reliable components in sensitive electronic circuits.

Ordering Information

To facilitate specific requirements, KEMET provides a flexible selection process, including options for case size, capacitance, and voltage rating to identify the preferred component. Variations in packaging and termination finishes are available, and custom solutions can be discussed with KEMET directly.

Applications

These MLCCs are versatile for a multitude of applications such as timing, tuning, low loss and high current circuits, energy storage, and more, given their non-polarity and temperature resilience.

Environmental Compliance and Certification

All commercial grade products meet internal quality standards, which are detailed in KEMET’s referenced Performance and Reliability table. They also comply with environmental and safety regulations, being free from lead (Pb), and adhering to both RoHS and REACH without exemptions. Customers can thereby trust in the responsible manufacturing and consistent performance of these capacitors.
