Murata has introduced the LXES series of ceramic and silicon based ESD protection devices. Both types feature high suppression levels, high repetition durability and ultra-low capacitance for use in high speed data transmission environments. ESD protection devices are critical components in protecting sensitive circuits in electronic equipment such as mobile phones, notebook PCs and netbooks, digital cameras and other consumer devices from electrostatic discharge (ESD).

With increased demand for more features in mobile devices, and reduced feature size in today's ICs, preventing damage from electrostatic discharge has become even more of a challenge, as many solutions suffer from insufficient or degraded suppression characteristics after repeated electrostatic discharges. Murata solved these problems by enhancing the aforementioned characteristics and repetition durability through the original product design.

Silicon based parts in the LXES series feature a low capacitance design (down to 0.25pF typical), which also minimises signal loss on high speed data and transmission lines. Additional features include high suppression levels (less than 100V output when input voltage is 15kV) and high repetition durability (1000 cycles at 8kV contact voltage). The product series includes two, four and six line array designs, along with single line devices.

Ceramic parts in the LXES series also feature ultra-low capacitance (down to 0.05pF typical) and small case size, down to 1.0 x 0.5 x 0.33mm. Crucially, the ceramic devices produce very little distortion (under -100dBm at 800MHz) making them suitable for use in antenna circuitry. They also feature high repetition durability (1000 cycles at 8kV contact voltage).
