IQD responds to demand for higher temperature crystals
Operating at a temperature range of -40 to +125 degrees, IQD has introduced a range of crystals housed in popular four-pad surface mount packages for use in industrial and automotive applications.
Components capable of withstanding high operating temperatures are increasingly in demand, and not just by engineers working on the traditional high temperature or extreme projects, such as downhole applications, said the company. IC manufacturers, who often design one chipset suitable for both industrial and automotive applications, are also requested these devices. Demand is also driven by the increased use of electronic devices in more extreme environments. Another trend is that internal self-heating of electronic components placed close to the crystal on the board need to guarantee operate within the specification up to 125 degrees C.
Customers who are using the same frequencies in multiple projects with different temperature requirements may also benefit from selecting one extended temperature part that is designed to work within all these applications rather than having to source and stock multiple parts, advised IQD.
The company offers a range of crystals in four-pad surface mount ceramic packages. The CFPX-180 measures 3.2 x 2.5mm and the IQXC-42 measures 2.0 x 1.6mm and have an extended operating temperature range of -40 to +125 degrees C.
The CFPX-180 is available in a range of frequencies from 12.0 MHz and the IQXC-42 from 16.0 MHz, with various load capacitances. The parts are offered with frequency stabilities down to +-30ppm over the temperature range. The ESR values are specified slightly lower than for the existing range of crystals in order to meet the demands of new microcontrollers, which often require lower ESR, for example for IoT applications.
For engineers requiring AEC-Q200 qualification, IQD also has a range of automotive qualified crystals.
The surface mount devices are recommended for multiple applications, including Ethernet, green and smart energy applications, including solar inverters, industrial control systems, RFID, test and measurement systems, telemetry and transportation systems and wi-fi modules.
