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, offering an operating temperature range of -55°C to +125°C. They are classified as a Class I material by the Electronics Components, Assemblies & Materials Association (EIA), indicating they are temperature compensating and ideal for resonant circuit applications or where high Q factor and capacitance stability are necessary. These capacitors are notable for experiencing minimal capacitance fluctuations over time, voltage, and ambient temperature changes, ensuring a steady performance with a capacitance change limited to ±30 ppm/°C.

Benefits

The SMD MLCCs offer several advantages including their compliance with Lead (Pb)-free, RoHS, and REACH regulations. They come in a wide range of case sizes from EIA 0201 to 2225, to fit various applications, and provide a broad spectrum of capacitance values from 0.5 pF to 0.47 µF. Additionally, these capacitors are available with various tolerance levels ranging from ±0.10 pF to ±20%. They exhibit no piezoelectric noise, very low Equivalent Series Resistance (ESR) and Equivalent Series Inductance (ESL), high thermal stability, and a significant ripple current capability.

Ordering Information

The datasheet includes guidance on how to order the correct capacitor by breaking down the Ordering Information into case size, capacitance, voltage rating, dielectric, tolerance, packaging, and failure rate. The capacitors come with a DC voltage rating that spans from 10 V to 250 V. The capacitance is represented through the designation code, where the first two significant digits, followed by the number of zeros, indicate the capacitance value in picofarads (pF). For example, a capacitance of 2.2 pF is shown as 229, and 0.5 pF as 508. Options include flexible termination, and additional tolerance and termination finishes may be available upon contacting KEMET.
