AC-line-rated ceramic disc capacitors save space
Vishay Intertechnology has revealed 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 (760VAC) and Class Y1 (500VAC) applications in accordance with IEC 60384-14, 4th edition, the devices have been hailed by the manufacturer as the industry's first to offer capacitance up to 20nF.
With their high capacitance range, the 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 to +125°C.
The 20nF capacitors consist of two silver-plated ceramic discs with tinned copper connection leads offering 0.81mm diameters. 440L series devices are available with radial kinked or straight leads with spacing of 9.5mm. 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.
