Industry’s First High Capacitance, High Voltage SMD Ceramic Safety Capacitors

Vishay Intertechnology introduces a new series of surface-mount AC line rated ceramic disc safety capacitors that are the industry’s first such devices to offer a Y1 rating of 500 VACand 1500 VDC. Designed to withstand harsh, high humidity environments, the Vishay BCcomponents SMDY1 series devices offer industry-high capacitance to 4.7 nF.

Product Benefits:

• Y1 rating of 500 VACand 1500 VDC
• High capacitance to 4.7 nF
• High humidity robustness with a Class IIB humidity grade (in accordance with IEC60384-14 annex I) and a moisture sensitivity level of 2a
• RoHS-compliant and halogen-free
• The closest competing devices only offer capacitance up to 1.5 nF and Y1 ratings to 300 VAC, with no DC rating
• Allowing for surface-mount assembly with a reflow soldering process, SMDY1 series capacitors reduce production costs
• Compared to through-hole devices, the capacitors offer a lower profile and eliminate the need for clearance space on the backside of the PCB
• Consist of a copper-plated ceramic disc and feature encapsulation made of flame-resistant epoxy resin in accordance with UL 94 V-0.

Applications:

• EMI / RFI filtering in power supplies, solar inverters, smart meters, and LED drivers
