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.

AEL Crystals Limited is one of the UK's largest suppliers of quartz based frequency control components. Established since 1960 as a specialist in the field of quartz frequency control products, this makes us also one of the longest existing companies in this field. This is a testament to our dedication and our technical expertise and customer service.

Our products have gained universal recognition throughout the world, within applications as diverse as Set-Top Boxes, Security Products, Automotive Products and Mobile & Terrestrial Communications.
