Weartech-Components & Hardware

Based on breakthrough ESD technology, the XGD Series Xtreme-Guard ESD suppressor are available in 0402- and 0603-sized, flat-topped surface mount packages from Littelfuse.
They protect sensitive electronics against ESD as high as 30kV and are suitable for high voltage applications up to 32V DC. They can absorb repetitive ESD strikes nearly four times the maximum level specified in the IEC61000-4-2 international standard without performance degradation, claims the company. Extremely low capacitance makes them suitable for use in high-frequency and high-speed data, video, antenna and I/O circuits.
According to the company, even after multiple ESD strikes, it exhibits low current leakage (less than 1nA), ensuring minimal power losses, for battery-powered electronics, like wearables. Both sizes offer much higher voltage ratings than other ESD suppressors with similar board footprints, claims the company and they offer greater ESD protection than many TVS diodes while providing lower capacitance and leakage current and higher voltage ratings.

Round TFT touch screens aimed at the growing market for wearable electronics, especially in the healthcare and fitness sectors, are now available from AndersDX.

Launched at APEC Power Conference, the SC33020H load switch is just 0.9 x 0.9mm and housed in a four-bump CSP (chip scale package) and what the company describes as industry leading Ron of just 32m‡.
