Vishay Intertechnology has introduced a series of surface-mount multilayer ceramic chip capacitors (MLCCs) optimised for high-voltage industrial and telecomms applications. Providing increased reliability over standard devices, the Vishay Vitramon HV High Voltage Series features a robust serial electrode design and an extended voltage range up to 5kV in four standard EIA sizes from 1812 to 2225.

The higher breakdown voltage of the MLCCs released today increases reliability against voltage spikes, while their serial electrode design reduces the risk of short circuits due to mechanical cracks. Manufactured in Noble Metal Electrode (NME) technology with a wet build process, the devices are suitable for input and output filtering in power supplies and analogue and digital modems, snubbing in power converters and buffering in voltage multipliers.

Featuring an X7R dielectric, HV High Voltage Series devices offer a voltage range from 3000 to 5000VDC, capacitance from 180pF to 15nF, a Temperature Coefficient of Capacitance (TCC) of ± 15 % from -55 to +125°C and an aging rate of 1% maximum per decade. RoHS-compliant, halogen-free and Vishay Green, the MLCCs offer 100% matte tin plate terminations.
