The 1812GC472KAT1A is a Multilayer Ceramic Capacitor with Ni/Sn-plated termination, X7R dielectric and 1812 case. The high value, low leakage and small size are difficult parameters to obtain in capacitor for high voltage systems. The standard high voltage MLC chip capacitor meets this performance characteristic and is designed for applications such as snubbers in high frequency power converters, resonators in SMPS and high voltage coupling/DC blocking. Larger physical sizes than normally encountered chips are used to make high voltage MLC chip products. The temperature gradient during heating or cooling cycles should not exceed 4°C per second. The preheat temperature must be within 50°C of the peak temperature reached by the ceramic bodies through the soldering process.

High voltage chip designs exhibit low ESRs at high frequencies

The Murata GRM series capacitors are Multilayer Ceramic Chip Capacitors (MLCC) used for general purpose applications. These MLCC capacitors are classified into temperature compensating and high dielectric constant types depending on the change in electrostatic capacitance due to change in temperature. The temperature compensating capacitors feature a small rate of change in electrostatic capacitance as the temperature changes and are used for applications such as filters and high frequency circuit matching. The high dielectric constant capacitors use materials with a high dielectric constant and feature a large electrostatic capacitance. Typical applications are power supply decoupling and smoothing circuits.
