Vishay’s New High-Voltage SMD MLCCs Deliver High Reliability for Industrial and Telecom Applications

Vishay New High Voltage

Vishay unveils a new series of surface-mount multilayer ceramic chip capacitors (MLCCs) optimized for high-voltage industrial and telecom applications. Claiming high reliability over standard devices, the Vishay Vitramon HV High Voltage Series features a robust serial electrode design and an extended voltage range up to 5 kV 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. Manufactured in noble metal electrode (NME) technology with a wet build process, the devices are ideal for input and output filtering in power supplies and analog 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 VDC to 5000 VDC, capacitance from 180 pF to 15 nF, a temperature coefficient of capacitance (TCC) of ± 15 % from -55 °C 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.
