AVX offers designers the ability to clamp transients and filter EMI in one ultra compact device with the expansion of its Transguard multilayer varistor series. Designed for all small handheld devices, the miniature 0201 bi-directional transient voltage suppressor provides minimal signal distortion and low insertion loss.

In addition to developing an advanced MLV that is miniature in size, the
Transguard 0201 can decrease the chip count on printed circuit boards,
reducing the amount of real estate needed, said Sonja Brown, global product
manager for circuit protection products at AVX. The MLV is a
cost-effective product that solves our customers increased need for a
circuit protection device that meets space constraints and provides superior
protection versus larger components.

The Transguard 0201 multilayer varistors are ideal for handheld devices
including cell phones and PDAs, as well as embedded components such as
hearing aids and camera modules.

Initial offerings of the miniature Transguard Series includes 15pf and 33pf
capacitance devices with a 5.6V rating in an 0201 case size. These products
have multiple strike capability and are able to withstand 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 8 weeks.
