Murata Electronics GR4 Chip Monolithic Ceramic Capacitors offer a 2000VDC rated voltage, 100pF to 10,000pF capacitance range, and 5.7mm x 5mm maximum size. The GR4 series features a monolithic structure that enables small, high capacitance and is capable of operating at high voltage levels. The tin-plated electrodes realize good solderability, and these capacitors are only for reflow soldering. Murata Electronics GR4 Chip Monolithic Ceramic Capacitors are ideal for us as primary-secondary coupling for DC-DC converters and use on telecommunication devices in Ethernet LAN.
