QVS TECH INC has been successfully supplying high quality Frequency Control Products for over 20 years.   As a Women Owned Small Business headquarters in Carlsbad CA, QVS TECH INC has established a reputation of providing superior service to our customers and quick deliveries.

Chairman and CEO, Mr Arthur Lee established the parent company, Kolinker Industrial Equipments, Ltd. in 1983. The main strategic focus was on designing and producing quartz crystal equipment. The motto of the company is to act as a CORE of various up-to-date high technologies and to LINK these technologies to specific fields of industry: the CORE-LINKER, hence KOLINKER.

By 1989, the Group diversified into the quartz crystal manufacturing and trading and Hong Kong X’tals Ltd was formed in 1991. The global brand “HKC” has since gained wide recognition in global automotive, electronic networking and industrial/consumer electronic appliances industries. All the production plants at Zibo, Qingdao and Shenzhen in China are endowed with QS9000 and TS16949 certification.

PETERMANN-TECHNIK’s cornerstones are support, delivery, quality, reliability and cost reduction.  We invite all our customers to benefit from our performance enabling them to develop securely working end-products by using our high quality and extremely long life frequency controlled products.  Draw your possibilities and savings potentials.

The Connor-Winfield Corporation is a privately held, US based electronic product manufacturer. After incorporation in 1963, Connor-Winfield focused primarily on designing and manufacturing quartz based timing circuits and oscillators for use in a wide variety of electronics applications. In the 1990's, Connor-Winfield expanded into other product areas while maintaining a continued focus on its core timing roots.

Connor-Winfield's frequency control products are used in a wide variety of applications including telecommunications, LAN and WAN products, computer, and other microprocessor and electronic equipment. We specialize in designing custom and semi-custom frequency control products but also offer a broad line of standard oscillator products and non-crystal based oscillators.

自1881年成立以来，精工推出了一款又一款革命性的产品，包括1913年日本首款腕表和1969年全球首款石英表。合并后的公司现在在广泛的领域开展业务，从手表到电子设备、半导体、眼镜、钟表和其他产品。这些个体企业中的每一个都致力于通过其业务联盟实现进一步的飞跃。

Since its founding in 1881, Seiko has introduced one revolutionary product after another, including the first wrist watch in Japan in 1913 and the first quartz watch in the world in 1969. The consolidated companies now operate in a broad range of fields, from watches to electronic devices, semiconductors, eyewear, clocks and other products. Each one of these individual businesses strives for further leaps forward through its business alliances.

关于 RTC你知道多少 ,ECS-320-18-33-JGN-TR晶振，要了解什么是实时时钟（RTC）以及它是如何工作的，重要的是要从频率开始。当共振表面（例如石英晶体）被机械搅拌（如振荡）时，会产生频率。

如果设计正确，有源晶振可以产生 32.768 kHz 的频率。这个频率是理想的，因为在质量工程的帮助下，它允许精确的、一秒钟长的脉冲。因此，如果设计得当，晶体振荡器可以创建可靠的时钟。当然，这种工程配置在石英表中使用得最为著名。
