Syfer – Innovative MLCCs dramatically increase maximum capacitance values (X7R Multilayer Chip)

The world-wide launch of Syfer’s latest new product family, set to revolutionise the world of large-size high voltage X7R Multilayer Chip Capacitors (MLCCs), will take place at Electronica 2012 in Munich, says the company.

The StackiCap X7R devices dramatically increase the maximum capacitance values now possible in larger case sizes, thereby delivering the potential to significantly reduce printed circuit board real estate.

Syfer has developed a highly-innovative patented technique (GB patent No. 1210261.2) to reduce electro-mechanical stresses in the body of the component, allowing for the consistent and reliable volume production of thicker and larger size devices.

The first parts to become available in the StackiCap family will be 1812 and 2220 case sizes, with 200V to 1kV and 500V to 3kV operating voltage ranges respectively. Claiming an industry first, Syfer’s 2220 500V device features 1µF capacitance in a single chip. The 3kV part also features an impressive 33nF capacitance previously found only in the much larger 5550 case size.

Meanwhile, in the 1812 range, the 200V part also features 1µF capacitance, while the 1kV device features 150nF capacitance, previously only possible in larger size components.

The StackiCap devices are expected to appeal to designers of any high-voltage products where space is at a premium and maximum capacitance is required. Typical applications include power supplies, projector modules, lighting systems and throughout the aerospace sector. In some instances, the parts will allow for a size reduction from 8060 to 2220, providing a factor of 10 saving in board space. In addition, designers will see further benefits, including reduced component count, and lower assembly costs as devices can be supplied in standard tape and reel format. Designed at Syfer’s UK based engineering centre, the range is expected to expand up to the 8060 case size.

Parlez on passives – Electronica 2012 – Technical experts will be on hand at the Syfer Technology stand Hall B6, Booth 336 to discuss specific and specialist needs for passive components and EMI filtering. Custom devices are often possible if the precise part required is not in its extensive range, says the company.
