AVX Corporation 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 will decrease chip count, reducing the amount of PCB real estate needed”, said Sonja Brown, global product manager for circuit protection products. “The MLV is a cost-effective solution that meets our customers’ increasing needs for a circuit protection device that meets space constraints yet provides superior protection versus larger components.”

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 Transguard 0201 MLV availability includes 15pF and 33pF capacitance devices with a 5.6V rating. These products are able to withstand 1,000 strikes at 8kV and feature a response time of under 1ns. The devices have a leakage current of less than 5µA at rated voltage.
