AVX 0603 MLCC seriesX7R formulations are called “temperature stable” ceramics and fall into EIA Class II materials, and COG (NPO) is the most popular “temperature-compensating” EIA Class I ceramic materialsMultilayer Ceramic Capacitors whose temperature variation is within ±15% from -55°C to +125°CThe capacitance change is non-linearCapacitance for X7R varies under the influence of electrical operating conditions such as voltage and frequencyAVX high voltage chips have advantages of high value, low leakage and small size, thus applications include as snubbers in high frequency power converters, resonators in SMPS and high voltage coupling/DC blockingThese high voltage chip designs exhibit low ESRs at high frequenciesReduced noise X5R versions available
