AVX - X7R 电介质多层陶瓷电容器

AVX 的 X7R 电介质 MLCC 提供电容器的“温度稳定”范围，可在 -55°C 至 +125°C 的广泛工作温度范围内使用。这些电容器应用广泛，非常适合电容随外加电压变化的应用场合。

特点和优势

在 -55°C 至 +125°C 范围内电容 ±15%
电容器的“温度稳定”范围

应用

可用于电容变化的广泛工业应用场合

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.
