YIC was established in Taiwan in 1994 and is a major manufacturer and designer of frequency control and GNSS/RF products. It serves as a director and supervisor of PCIAT (Taiwan Piezoelectric Crystal Industry Association). The factory is located in Yantai, China, and is one of the few factories in the world that has a process starting from the cutting of crystal oscillators Y and Z bars. The GU-903 series features a USB interface and is a compact, low-power GPS module with high performance. Product Features: • Embedded SPI flash • High-performance, low-power GNSS chipset • Extremely high sensitivity • Achieves very fast TTFF (Time To First Fix) at low signal levels • Chipset protocol • Built-in LNA • LED display for GPS status • Custom printing markings available Additionally, it uses a highly utilized chipset from u-blox, making it easy to operate and providing high reception sensitivity due to the built-in low-noise amplifier.

Bourns has developed an innovative GMOV hybrid overvoltage surge protection component that outperforms conventional MOV components in terms of performance and reliability. The innovative GMOV component combines metal oxide varistors (MOV) and gas discharge tubes (GDT) with patented space-saving FLAT technology. This hybrid device has a compact shape and can be used instead of standard 14 or 20 mm MOVs. **Performance** - Zero energy consumption in standby - Low capacitance - GDT isolates MOV from AC/DC - Isolates MOV from line voltage below GDT turn-on voltage - Low leakage current over the lifespan (<0.1 µA) In general, GMOV components for overvoltage protection can be used in nearly any application powered by AC or DC. The GMOV hybrid overvoltage protection system has been tested and evaluated, proving effective against various hazards encountered in the field.
