Fort Myers, Fla. Fox Electronics touts that a new quartz crystal packaging technology provides a cost reduction of up to 20% or more over conventional ceramic packaging, and eliminates the recurring problems of ceramic shortages. The new FQ series, utilizing the proprietary crystal packaging technique, is initially offered in three popular crystal package sizes, each available in 2- or 4-pad configurations.
In addition, the FQ series offers low profile construction as well as a weight savings over ceramic packages. The new crystals are fully RoHS compliant and offer complete pad compatibility with existing ceramic packages. The new devices include the 10 x 4.5 mm (FQ1045), 5 x 7 mm (FQ7050) and 6 x 3.5 mm (FQ6035), with smaller sizes now under development. Developed to effectively combat both cost and availability pressures, the new crystals yield costs savings of 15% in quantities of 10,000 to 20,000, and savings of 20% in quantities of 50,000, said the company.
Depending on the package size, the crystals are available in frequencies from 3.2 MHz to 49 MHz, with a 30-ppm tolerance at 25°C. Standard stability is 30 ppm over the temperature range of 0°C to 70°C. Tighter stabilities are available on special order. The devices are also available with an extended temperature range of -40°C to 85°C. These devices are suitable for a wide range of applications including hard disk drive, PDAs, set-top boxes and security systems.
Pricing for the FQ7050 crystal (5 x 7 mm with a frequency of 8 MHz) is $0.19 ea. in quantities of 50,000. Delivery is six to eight weeks.
