New XRQ Crystals Introduced by Diodes Incorporated

The new XRQ crystals were introduced by Diodes Incorporated. These are automotive compliant series and timekeeping crystals that resist insensitive working conditions to make sure excellent accuracy as well as consistency within infotainment, TPMS (tire-pressure monitoring systems), telematics & ADAS (advanced driver assistance systems).

These crystals are capable of constant act up to 1500g centrifugal forces, the novel XRQ crystals exceed the specification of SAE J2657 (Society of Automotive Engineers) for tire-pressure monitoring systems. At present, a fixed security feature designed for new cars promoted in global regions.

The crystals like XRQ series are opposed to shocks up to 8000gt. But these are extensively superior to the typical (1500g). These are also exceeded drop tests based on JIS-C0044 industry by fall of surviving up to 1.2 meters.


The XRQ crystals meet up the process requirements of ultrasonic welding manufacturing. These processes are cleaner compare with conventional processes. It is used as manufacturing hermetically preserved objects like a TPMS. This method is used to make automotive components to offer higher precision and consistency.

These crystals are appropriate for automotive applications like beneath the hood & in locations of traveler compartment. This crystal is qualified by AEC-Q200 & accessible in the range of temperatures like Grade-1 (-40°C -125°C), Grade-2 (-40°C-105°C), & Grade-3 (-40°C – 85°C). The crystal devices are PPAP (production part approval) capable & are assembled in qualified amenities like IATF16949.

Three typical sizes are obtainable. XR32Q variations within the 3.2mm × 2.5mm outline are obtainable within the frequencies range 12MHz – 66MHz. The XR25Q devices variations within the 2.5mm × 2.0mm outline are obtainable within the frequencies range 16MHz – 66MHz.


The XR20Q devices variations within the 2.0mm × 1.6mm outline are obtainable within the frequencies range 24MHz to 66MHz. The surface-mount of ceramic packages is seam-sealed intended for mechanical integrity & hermeticity.

The applications of XRQ Crystals mainly include TPMS (Tire-pressure monitoring system), telematics, infotainment, and ADAS (Advanced driver assisted system).
