Industry's First SMD Y1 Safety Capacitors with 500Vac & 1500Vac Ratings

Product Benefits:

  • Y1 rating of 500 VAC and 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

Market Applications:

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

The Details:

  • Vishay Intertechnology is proud to introduce 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 VAC and 1500 VDC

  • Designed to withstand harsh, high humidity environments, the Vishay BC Components SMDY1 series devices offer industry-high capacitance to 4.7 nF

  • 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

The Key Specifications:

  • Series SMDY1 Ceramic class 2 Ceramic dielectric Y5U Voltage (VAC) Y1: 500 (1500 VDC) X1: 760 Min. capacitance (pF) 470 Max. capacitance (pF) 4700 Capacitance tolerance (%) ± 20 Mounting Surface mount

  • Samples and production quantities of the SMDY1 series will be available in Q1 2021, with lead times of 10 weeks.
