C1812C474K5RAC7800 – KEMET

Overview

The KEMET C1812C474K5RAC7800 is a high-performance 0.47 µF, 50 VDC multilayer ceramic capacitor (MLCC) featuring an X7R dielectric. This component excels in applications demanding stable capacitance over a wide temperature range, crucial for maintaining signal integrity in sensitive circuits. A key design consideration with X7R dielectrics, however, is their susceptibility to capacitance change with applied DC voltage (voltage coefficient), which engineers must account for during component selection to avoid performance degradation in high-bias scenarios.
