Established in 1995, Interquip Electronics is a comprehensive high-tech enterprise in R&D, manufacturing and marketing high precision Quartz Crystal Resonators (including Thermistor Crystals and 32.768KHz Tuning Fork Crystals) and Oscillators (including TCXO, VCXO, LVDS/LVPECL output waveform XO, programmable Oscillators etc.). The frequency components produced can be widely applied in 5G Smart Home, Smart Wear, IoT, IoV, Consumer Electronics, Telemedicine, Automotive Electronics (conforms to AEC-Q200), Communication Industry, Security Applications, Industrial Equipment and other industries.

The size of crystal resonators and oscillators ranges from 1.2 x 1.0mm to 7.0 x 5.0mm package, frequency available from 32.768KHz to 200MHz. With an annual production capacity of more than one billion frequency control components, Interquip has its crystal products exported to Europe, North America, Asia Pacific and other regions.

MERCURY Electronic Ind Co., Ltd. has a 40-year history and is the first manufacturer in Taiwan to manufacture quartz crystals. However, the quartz crystal products used in the electronics industry have undergone great evolution, and the size has been miniaturized. The package has also changed from lead type to surface mount type, and the frequency range has been expanded to several KHz to several hundred MHz, and the precision is also calculated in parts per million. Its function is also extended to electronic communication intelligence and aerospace technology.

With the needs of the market, the company continuously improves and researches and develops new products and production technologies, and pursues stable and excellent quality in order to meet the requirements of customers.
