Ceramic Disc Capacitors Save Space With Extended Capacitance to 20nF

Vishay Intertechnology announced that it has extended the capacitance range of its 440L series of AC-line-rated ceramic disc capacitors. Designed 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 the industry's first to offer capacitance up to 20 nF.

With their high capacitance range, 440L series capacitors 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 released today 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 available now. Production quantities will be available in Q2 2016, with lead times of eight weeks for larger orders. Pricing for U.S. delivery starts at $1.00 per piece for 20 nF devices.
