Controlled Capacitance
Multilayer Varistor
GENERAL DESCRIPTION
The Controlled Capacitance TransGuard is an application specific bi-
directional transient voltage suppressor developed for use in mixed signal
environments. The Controlled Cap MLV has three purposes: 1) reduce
emissions from a high speed ASIC, 2) prevent induced E fields from
conducting into the IC, and 3) clamp transient voltages
By controlling capacitance of the MLV, the center frequency and 20db
range for filtering purposes can be targeted. A Controlled Cap MLV can
greatly improve overall system EMC performance and reduce system
size.
Operating Temperature: -55oC to +125oC
