X7R 配方称作温度稳定陶瓷，属于 EIA II 类材料，COG (NPO) 是最常用的温度补偿EIA I 类陶瓷材料
多层陶瓷电容器，-55°C 至 +125°C 时温度变化在 ±15% 内
电容变化为非线性
AVX 高电压芯片具有高值、低泄漏和小尺寸的优势，因此应用包括：高频功率转换器中的减震器、SMPS 中的共振器和高电压耦合/直流阻隔
这些高电压芯片设计在高频时具有低 ESR
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.
