Vishay Intertechnology’s Compact 440L Series AC-Line-Rated Ceramic Disc Capacitors with Extended Capacitance to 20 nF

Vishay 440L Series

Vishay Intertechnology announces that it has extended the capacitance range of its 440L series of AC-line-rated ceramic disc capacitors. Tailored to provide high reliability for Class X1 (760 VAC) and Class Y1 (500 VAC) applications in accordance with IEC 60384-14, 4th edition, the Vishay Cera-Mite devices are claimed to be industry’s first to offer capacitance up to 20 nF.

Coming in high capacitance range, 440L series capacitors is touted to save board space in antenna coupling, line bypass, across-the-line, and RFI filtering applications for power and smart meters, lighting ballasts, and consumer products. Featuring C0G, U2J, P3K, R3L, X7R, and Y5U ceramic dielectrics, the devices feature tolerances down to ±10 % and operate over a temperature range of -30 °C to +125 °C.

The 20 nF capacitors consist of two silver-plated ceramic discs with tinned copper connection leads offering 0.81 mm diameters. 440L series devices are available with radial kinked or straight leads with spacing of 9.5 mm. RoHS-compliant, the capacitors’ encapsulation is made of flame-resistant epoxy resin in accordance with UL 94 V-0.


Samples of the extended 440L series are exclusively obtainable. Production quantities will be available in Q2 2016, with lead times of eight weeks for larger orders.
