Vishay Intertechnology Inc. has announced a line-up of surface-mount multilayer ceramic chip capacitors (MLCCs) geared for high-voltage industrial and telecom applications. The Vishay Vitramon HV High Voltage series claims to deliver increased reliability over standard devices and 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 increases reliability against voltage spikes, while their serial electrode design reduces the risk of short circuits due to mechanical cracks, noted Vishay.

Vishay Vitramon HV High Voltage series

Manufactured in noble metal electrode (NME) technology with a wet build process, the devices are aimed at input and output filtering in power supplies and analogue and digital modems, snubbing in power converters, and buffering in voltage multipliers.

Featuring a X7R dielectric, HV High Voltage series devices offer a voltage range from 3kVDC to 5kVDC, capacitance from 180pF to 15nF, a temperature coefficient of capacitance (TCC) of ±15 per cent from -55°C to 125°C, and an aging rate of one per cent maximum per decade. RoHS-compliant, halogen-free and Vishay Green, the MLCCs offer 100 per cent matte tin plate terminations.

Samples and production quantities of the HV High Voltage series are available with lead times of 11 weeks.
