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

Category: Capacitors, Electronics, Kemet Electronics Corporation

Overview

The featured datasheet presents information about KEMET’s commercial grade surface mount multilayer ceramic chip capacitors (SMD MLCCs) with COG dielectric, supporting a voltage range from 10 VDC to 250 VDC. The COG dielectric is identified by the Electronics Components, Assemblies & Materials Association (EIA) as a Class I material, which is noted for its temperature compensating attributes. These components are designed to be stable, making them suitable for resonant circuit applications where constant Q factors and steady capacitance characteristics are essential. The COG dielectric offers stable capacitance over time and voltage with a minimal capacitance shift in response to ambient temperature variations, capped at ±30 ppm/°C within a temperature span from -55°C to +125°C.

Benefits

Key advantages of these capacitors include a wide operating temperature range (-55°C to +125°C), lead (Pb)-free construction, compliance with RoHS and REACH regulations, and availability in various EIA standard case sizes. These range from 0201 to 2225, accommodating different physical design requirements. Voltage ratings extend from 10 V to 250 V, and capacitance values span from 0.5 pF to 0.47 µF. Capacitance tolerances offered include +0.10 pF, +0.25 pF, +0.5 pF, +1%, +2%, +5%, +10%, and ±20%, providing options for precision demands. Additional features of these capacitors are the absence of piezoelectric noise, extremely low equivalent series resistance (ESR) and equivalent series inductance (ESL), high thermal stability, and capability to handle high ripple currents.

Ordering Information

Ordering KEMET’s capacitors involves selecting the appropriate case size, specification or capacitance code, capacitance tolerance, dielectric type (COG), voltage, and finish options. The datasheet illustrates the identification system for each element; for instance, the capacitance is denoted by two significant digits followed by the number of zeros, with special indication for sub-1 pF ranges. Tolerance is signified by letters from B to M, each corresponding to a specific deviation range. Voltage ratings are encoded as single digits denoting specific voltage levels (e.g., ‘8’ for 10V, ‘4’ for 16V, up to ‘A’ for 250V).

Additionally, it’s mentioned that flexible termination options are available, as detailed in the FT-CAP product bulletin. KEMET also suggests contacting them directly for additional capacitance tolerances and termination finish options not listed in the datasheet.
