IQD introduces new quartz crystal range designed for space and cost savings
1 min read
IQD has launched two new quartz crystal models designed to deliver significant space and cost saving whilst still utilising tried and tested technology.
The new surface mount IQXC-74 measures 7 x 4mm with a height of 2.3mm – this compares with the similar current industry standard HC49/4HSMX design which measures 11.4 x 4.9 x 4.3mm. Whilst IQD's latest ceramic package designs do offer smaller dimensions than this, they are significantly more expensive due to the artificially high cost of the ceramic packaging. The company says the IQXC-74 offers an attractive compromise at significantly lower cost.
IQD is also launching a thru hole version, the IQXC-75 which is even smaller at 6 x 4 x 1.8mm with similar benefits.
Frequencies are available from 12 to 40MHz over operating temperature ranges as wide as -40 to 85°C. Frequency tolerances and stabilities over the operating temperature range are available down to 10ppm. Drive level power consumption ranges from 10 to 100µW and shunt capacitance is rated at 5pF max. Frequency range changes due to aging are specified at ±5ppm in the first year.
Both models are housed in hermetically sealed metal can packages and can be supplied in tape and reel form to support use in automated assembly manufacturing processes.
