Syfer introduces Protecticap

Protecticap

MLCCs are particularly suitable for high voltage applications where small size is required. For standard high voltage capacitors a coating may be required to be applied postsoldering, to minimise the risk of flashover from one termination on the chip to the other.

By contrast, the new ProtectiCap™ high voltage range has been introduced to specifically address this issue. The integral coating minimises the risk of flashover without any requirement for the customer to apply conformal coating after soldering.

FEATURES

- High voltage flashover resistance

- High voltage / small case size, for example 3kV in 1206

- Voltage ranges up to 5kV

- Case sizes from 1206 to 2220

APPLICATIONS

- Power supplies

- Lighting ballasts

- Inverters / DC link

- General high voltage circuits

  • Miniaturization of HV applications: a solution for every Power Electronics Engineer

    StackiCap™ has been set to revolutionise the world of large, HV(200V – 2kV), X7R Multilayer Chip Capacitors (MLCCs)!

    It dramatically increases the max capacitance values within a size/voltage or can reduce chip sizes. They take up 1/10th of the current footprint dimension and save up to 9/10th of the weight of a stacked cap. The advantages are spectacular on any HV products where pcb space is at a premium and max. capacitance is required in a smaller footprint. Typical applications include power supplies, projector modules, lighting systems and throughout the aerospace sector.
