This document describes the ceramic disc capacitors from Vishay BCcomponents, model Y2-DN, with a rated voltage of 400/250 V (AC). They comply with the standards EN 132 400 and IEC 60384-14, and offer high reliability. The capacitors are suitable for applications such as across-the-line, line by-pass, and antenna coupling.
The DNEMI/RFI Y2-DN series are Class X1/Y2 safety ceramic disc capacitors designed for across‑the‑line, line‑by‑pass and antenna‑coupling applications. They are offered with kinked or straight leads, lead spacings of 7.5 mm or 10 mm, and comply with EN 132 400 and IEC 60384‑14.
The data sheet provides detailed electrical parameters such as capacitance range, rated voltage, dielectric strength, dissipation factor, tolerance, and operating temperature. It also includes mechanical dimensions, lead specifications, and packaging options (bulk, tape‑on‑reel, ammopack). This manual is written in Chinese.
