High voltage multilayer chip capacitors with built-in protective coating
Syfer’s ProtectiCap process applied to its high voltage range of mlccs has been developed specifically to address this issue. The integral coating, a matte tin layer over the nickel FlexiCap base termination, minimises the risk of flashover and avoids the need for the customer to apply conformal coating after soldering. Aimed at applications such as power supplies, lighting ballasts, inverters/DC link, and general high voltage circuits, the X7R dielectric ProtectiCap MLCCs offer a capacitance range from 100pF to 33nF, package sizes range from 1206 to 2220.
Typical devices include a 2kV MLCC in 1206 package with capacitance range of 100pF to 3.3nF, 2kV MLCC in 2220 package with capacitance range of 220pF to 33nF, 3kV device in 1880 package with 100pF to 3.3nF capacitance range, and 5kV MLCC in 2220 package with 220pF to 4.7nF capacitance range. Additional specifications include operational temperature range of -55 to 125C, temperature coefficient of capacitance typically at +/-15%, and insulation resistance of 100GOhms or 1000s, whichever is the least. This range is fully compliant with the RoHS and WEEE directives and parts are compatible with lead free solders.
