SMDY1 500 VAC Safety Capacitors

Vishay introduces the SMDY1 series of surface-mount, AC line-rated, ceramic-disc safety capacitors that offer a Y1 rating of 500 V_AC and 1500 V_DC. Designed to withstand harsh, high-humidity environments, the SMDY1 series devices offer industry-high capacitance of up to 4.7 nF. They can be used for EMI/RFI filtering in power supplies, solar inverters, smart meters, and LED drivers. In addition, the SMDY1 series offers higher humidity resistance with a class IIB humidity grade (in accordance with IEC60384-14 annex I) and a moisture sensitivity level of 2a.

Allowing for surface-mount assembly with a reflow soldering process, SMDY1 series capacitors reduce production costs. Compared to through-hole devices, they offer a lower profile and eliminate the need for clearance space on the backside of the PCB. RoHS-compliant and halogen-free, the components consist of a copper-plated ceramic disc and feature encapsulation made of flame-resistant epoxy resin in accordance with UL 94 V-0.

(All devices which are connected to the mains require Y1 safety capacitors)
