Superior quality crystal and frequency components, oscillators and filters
10 September 2002
Passive Components
Crystal Quartz Technology products are manufactured locally. According to the company, this enables a faster, more efficient service and, it adds, the prices are highly competitive and attractive to both local and internationally-based clients.
Specialist 'AT' cutting of the quartz crystals and the crystal specifications of each component determines the style and suitable package of each application. Crystal Quartz Technology can offer skilled technical advice and support for research and development projects. Its products are used in various market sectors such as mining, security networks, engineering, electronics, computers, aeronautics, etc. The precision cutting of CQT's quartz crystals, oscillators and filters offer a superior ratio of high performance, accuracy and tolerance in each product.
Crystal Quartz Technology was established in 1987, and operates to international standards. A proactive management approach ensures that all components produced in the CQT factory are of a high standard. The company has invested in world-class applications and offers micro-technology with surface mount components.
The company offers both traditional through-hole as well as the surface mount technology, giving greater choice of application for specific requirements. Its small size gives it the flexibility to respond to customer needs and urgent deadlines faster than larger establishments. For emergency requirements, it is able to supply within days, depending on application.
A technical tip: CQT reminds that your crystals are sensitive. Consider soldering applications, and take care that when heat is applied to or near the crystal component that it does not get adversely affected.
