Vishay Intertechnology has introduced a new series of AC line-rated ceramic disc safety capacitors designed for EMI and RFI suppression in industrial and high-voltage applications.
The Vishay BCcomponents SMDY1…S series features:
- Y1 safety rating of 300 VAC and 1500 VDC in a surface-mount package.
- The compact design reduces board space requirements by up to 40% compared with previous-generation devices, helping manufacturers develop smaller products.
With a Y1 rating, the new safety capacitors can bridge double or reinforced insulation. They also support use in DC networks of up to 1500 VDC in accordance with Annex H of the relevant IEC standard.
The SMDY1…S series exceeds the industry-standard insulation resistance requirement of 6000 M?, offering a minimum insulation resistance of 10,000 M?. The capacitors operate across a temperature range of -55°C to +125°C, extending the lower end of the standard -40°C to +125°C range.
For reliability, Vishay subjects every component to 100% production testing. The end-of-line process includes a five-point verification protocol covering AC voltage, capacitance, dissipation factor, insulation resistance, and final visual inspection.
The surface-mount construction supports pick-and-place assembly and reflow soldering, eliminating the manual soldering typically required for through-hole components. This helps simplify manufacturing and reduce production costs.
The safety capacitors comply with IEC 60384-14 and are certified by UL, CSA, VDE, ENEC, and CQC. They are also RoHS-compliant and halogen-free. Each device consists of a copper- and silver-plated ceramic disc with flame-resistant epoxy resin encapsulation rated UL 94 V-0.
The SMDY1…S series is available in A case sizes with capacitance values from 10 pF to 680 pF, and B case sizes ranging from 1000 pF to 1500 pF.

Key Applications Include
The single-layer capacitors are suitable for industrial motor drives, welding equipment, inverters, uninterruptible power supplies, rail power supplies, HVAC systems, LED drivers, and automotive charging stations. They can also be used in smart-home automation systems, computer switch-mode power supplies, AC/DC converters, and consumer appliances such as washing machines and refrigerators.
Availability
Samples and production quantities of the SMDY1…S series are available now, with lead times of 12 weeks.
