Kemet has released to market a range of commercial grade high voltage ceramic surface mount capacitors. These parts are designed for applications demanding reliability at high voltages, including: high voltage lamp circuits; ballast circuits for LCD and other fluorescent lighting; laser light source circuits; RF antenna transmitter circuits; snubber circuits; high voltage tank circuits/resonator circuits; high voltage supply filter circuits; high voltage coupling/DC blocking circuits; input protection for LAN/telecom products.
Kemet says that these high voltage surface mount ceramic capacitors use a 'cascading' or 'floating' internal electrode design, which effectively divides the voltage across the device into smaller voltages that each internal section of the capacitor can easily accommodate, thereby enabling high voltage rating capability. These ceramic capacitors include rated voltages from 500 to 3000 V in COG and X7R dielectrics. They are offered in EIA case sizes range from 0805 to 2225 with capacitance values from 1 pF to 0,22 µF.
These commercial grade high voltage ceramic capacitors have pure tin (Sn) plated terminations for good solderability and are RoHS compliant.
