Ceramic disc capacitors extended to save board space

The VY1 and VY2 series of AC line rated ceramic disc safety capacitors from Vishay Intertechnology are now extended by a Mini Size Series with Y5V ceramic dielectrics. Featuring body diameters down to 7.5 mm, the Vishay BCcomponents VY1…Y5V and VY2…Y5V are designed to save space, lower costs, and increase reliability for Class X1 (760 VAC) / Y1 (500 VAC) and Class X1 (440 VAC) / Y2 (300 VAC) applications, respectively, in accordance with IEC 60384-14.4.

The Y5V dielectric of the devices provides a higher dielectric constant, allowing for a reduction in diameter without losing capacitance value.

The VY1…Y5V and VY2…Y5V are optimized for RFI and AC line filtering applications in compact power supplies, power adapters for home automation devices, E-meters, home appliances, consumer electronics, and industrial equipment.

The Mini Size Series safety capacitors offer a capacitance range from 1,000 pF to 10,000 pF — with tolerances of ±20% — and may be operated from -40 °C to +125 °C.

The devices consist of a silver-plated ceramic disc with tinned copper-clad steel connection leads offering 0.6 mm diameters.

The capacitors are available with vertical (inline) kinked leads or straight leads with spacing of 10 mm or 12.5 mm for the VY1…Y5V and 5.0 mm, 7.5 mm, 10.0 mm, or 12.5 mm for the VY2…Y5V.

RoHS-compliant, halogen-free, and Vishay Green, the components' encapsulation is made of flame-resistant epoxy resin in accordance with UL 94 V-0.
