AVX 1206 MLCC Series X7R 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 materials Multilayer Ceramic Capacitors whose temperature variation is within ±15% from -55°C to +125°C
The capacitance change is non-linear
AVX 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 blocking
These high voltage chip designs exhibit low ESRs at high frequencies
