Quartz crystal suits limited space, says IQD Frequency Products
Claimed to be one of the world’s smallest quartz crystals, the IQXC-240 measures just 1.2 x 1.0mm and has a height of 0.33mm.
The IQXC-240 is available from IQD Frequency Products in frequencies between 36 and 80MHz. It is suitable for applications where space is at a premium such as IoT, VGA, USB and wi-fi, advises the company.
Frequency stabilities can be specified as low as ±10ppm over the commercial temperature range of -20 to 70°C and ±15ppm over the industrial temperature range of -40 to 85°C. The frequency tolerance can be specified down to ±7ppm. In line with the requirements of the latest generation of microprocessors, the load capacitance can be as low as 5pF.
The IQXC-240 is housed in a four-pad ceramic hermetically sealed package with an electron beam sealed metal lid, which helps to minimise the EMI radiation. The crystal is designed to be able to withstand shock levels of up to 1000G in accordance with IEC 60068-2-27. The IQXC-240 is available on tape and reel in accordance with EIA-481D.
