Extended Temperature Crystal
Components capable of withstanding high operating temperatures are increasingly in demand, and it is not just by engineers working on the traditional high temperature or extreme applications, for example downhole. 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's range includes crystals housed in the popular 4-pad SMD ceramic packages 2.0 x 1.6 mm IQXC-42 with the extended operating temperature range of -40 to 125°C. IQXC-42 is available in frequencies from 16.0 MHz to 72 MHz, with various load capacitances. The parts are offered with 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.
These parts are recommended for multiple applications, including Internet of Things (IoT and IIoT), e.g.:
- Ethernet
- Green and smart energy applications (Solar inverters)
- Industrial Control Systems
- RFID
- Test and Measurement Systems
- Telemetry systems
- Transportation systems
- WiFi modules
