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

Ceramic Capacitors exhibit low parasitics and excellent EMI filtering capabilities. In a multilayer configuration, they display high capacitance values and various voltage ratings over a wide temperature range. Multiple styles are available such as MLCC chips, leaded capacitors, stacked capacitors and capacitors that utilise unique geometries.

X7R formulations are called "temperature stable" ceramics and fall into EIA Class II materials. X7R is the most popular of these intermediate dielectric constant materials. Its temperature variation of capacitance is within ±15% from -55°C to +125°C. This capacitance change is non-linear.
