IQD extends range of -40 to 125°C crystal components

Components that can withstand high operating temperatures are in increasing demand, not just by engineers working traditional high temperature applications or other extreme applications.

This trend is partly driven by IC manufacturers, who often design one chipset suitable for both industrial and automotive applications, and by the increased use of electronic devices in more extreme environments. Additionally, the internal self-heating of electronic components close to the crystal on the board can be a motivation to select a crystal that is guaranteed to operate within the specification up to 125°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.

IQD is therefore introducing a range of crystals housed in the popular 4-pad SMD ceramic packages 3.2x2.5 mm (CFPX-180) and 2.0x1.6 mm (IQXC-42) with the extended operating temperature range of -40 to 125°C. The CFPX-180 is available in a range of frequencies from 12.0MHz and the IQXC-42 from 16.0 MHz, with various load capacitances. The parts are offered with frequency stabilities down to +-30ppm over -40 to 125°C and 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.

These parts are recommended for multiple applications, including IoT and IIoT:

  • Ethernet
  • Green and smart energy applications (Solar inverters)
  • Industrial Control Systems
  • RFID
  • Test and Measurement Systems
  • Telemetry systems
  • Transportation systems
  • WiFi modules
