Surface-Mount Varistor Reliably Staves Off ESD

The ZVE Series is a low-capacitance, surface-mount, multilayer varistor designed for ESD protection. High capacitance can distort or even block communications signals. Because the ZVE Series is a multilayer varistor, it is inherently bi-directional and can handle higher current than similarly-sized silicon-based and spark gap-technology products. The ZVE Series is suitable for low-speed Ethernet lines, RS485, IEEE 1284, USB 1.1, and non high-definition video and audio ports and cables. The ZVE Series is available in standard 0603, 0805, 1206, and 1210 chip sizes. Operating voltage is 18 V dc and clamping voltage is 50 V at 2 A. Capacitance ranges from 75 pF on the 0603 size to 400 pF on the 1210 size product. The surface-mount ZVE Series is available in standard 7” tape and reel packaging. Pricing varies with size and ranges from $0.085 each to $0.185 each in full reel quantities. STACKPOLE ELECTRONICS INC., Raleigh, N.C., (919) 850-9500.
