Globenewswire·2025-09-17 15:00

Core Viewpoint - Vishay Intertechnology, Inc. has launched a new series of Automotive Grade AC line rated ceramic disc safety capacitors, which are the first in the industry to feature a Y1 rating in a surface-mount casing, designed for EMI/RFI suppression in harsh environments [1][2]. Product Features - The SMDY1 Automotive Series capacitors have a Y1 rating of 500 VAC and 1500 VDC, with capacitance up to 4.7 nF, making them suitable for applications in electric vehicles (EV), hybrid electric vehicles (HEV), and plug-in hybrid electric vehicles (PHEV) [1][2]. - These capacitors are AEC-Q200 qualified and have a Class IIB humidity grade, capable of withstanding the 85/85/1000 h test, ensuring high humidity resistance [2]. - The capacitors allow for surface-mount assembly with a reflow soldering process, which reduces production costs and enables a low, flat profile on the PCB [3]. Compliance and Specifications - The components are RoHS-compliant and halogen-free, made from a copper-plated ceramic disc with flame-resistant epoxy resin encapsulation in accordance with UL 94 V-0 [4]. - The SMDY1 Automotive Series is available in two case sizes: C case with a creepage distance of 10 mm and D case with a creepage distance of 14.5 mm [4]. - Specifications include a ceramic class of 2, a dielectric of Y5U, a minimum capacitance of 470 pF, a maximum capacitance of 4700 pF, and a capacitance tolerance of ±20% [5]. Availability - Samples and production quantities of the SMDY1 Automotive Series are currently available, with lead times of 12 weeks [5]. Company Overview - Vishay Intertechnology, Inc. is a leading manufacturer of discrete semiconductors and passive electronic components, serving various markets including automotive, industrial, computing, and telecommunications [6].
