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.
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.
EMI / RFI filtering in power supplies, solar inverters, smart meters, and LED drivers
Samples and production quantities of the SMDY1 series will be available in Q1 2021, with lead times of 10 weeks.
