Multilayer varistor tips minimal signal distortion

AVX Corp. has expanded its miniature Transguard series of multilayer varistors (MLVs) to include 50pF versions in addition to the previously available 15pF and 33pF capacitance devices. The MLVs offer a 5.6V rating in a 0201 case size, and give designers the ability to clamp transients and filter EMI in one ultracompact device. Suited for small handheld devices, the miniature 0201 bi-directional transient voltage suppressor provides minimal signal distortion and low insertion loss.

"The unique construction of the miniature 0201 Transguard series enables dual functionality—clamping transients and filtering EMI in one device—which decreases the chip count on PCBs and reduces the real estate needed," said Sonja Brown, global product manager for circuit protection products at AVX. "The MLV is a cost-effective product that solves the designers' need for a circuit protection device that meets space constraints while providing superior protection."

The Transguard 0201 MLVs are ideal for handheld devices, including cellphones and PDAs, as well as embedded components such as hearing aids and camera modules.

These products have multiple strike capability up to 1,000 strikes at 8kV of contact. The Transguard Series features a sub-1nS response time to ESD strike. The devices have a leakage current of Typical pricing ranges from $0.005-$0.024 for standard commercial product depending on volume with a lead time of stock to eight weeks.
