Overview
KEMET’s SMD MLCCs with COG dielectric offer a maximum operating temperature of 125°C. This product is classified by the Electronics Components, Assemblies & Materials Association (EIA) as a Class I material and is considered stable. COG dielectrics are ideal for resonant circuit applications and where the consistency and stability of capacitance are essential. Capacitance remains unaffected over time and displays minimal change with variations in ambient temperature, limited to ±30 ppm/°C across the range of -55°C to +125°C.
Benefits
A key advantage to using KEMET’s COG dielectric capacitors is their broad operating temperature range, spanning from -55°C to +125°C. They are also compliant with Lead (Pb)-free, RoHS, and REACH standards, making them suitable for environmentally conscious production. In terms of size, they are available in various EIA case sizes from 0201 to 2225, and offer a range of voltage ratings from 10 V to 250 V. Capacitance offerings vary from 0.5 pF up to 0.47 pF.
Available capacitance tolerances include ±0.10 pF, ±0.25 pF, ±0.5 pF, ±1%, ±2%, ±5%, ±10%, and ±20%. Another benefit of these capacitors is the absence of piezoelectric noise, combined with extremely low Equivalent Series Resistance (ESR) and Equivalent Series Inductance (ESL), which contribute to high thermal stability and high ripple current capability.
Ordering Information
The ordering code for KEMET’s COG dielectric capacitors includes the case size (like 1206), followed by a specification/capacitance code (such as 104 for 0.1 µF), the capacitance tolerance (with codes like B for ±0.10 pF), the voltage rating (indicated by numbers like 8 for a 10 V rating), the dielectric type (G for COG), termination finish (like matte tin), and the grade (C-spec).
Additional options include the ‘FT-CAP’ flexible termination option, which can be found in product bulletin C1062_COG_FT-CAP_SMD. The ordering table may list additional capacitance tolerances and termination finish options as well.
