Short lead-time micro miniature crystal in small footprint

RFX Group, incorporating Laptech Precision, has released a new micro miniature ceramic packaged crystal with a footprint of only 2.05mm x 1.65mm and a height of just 0.45mm. Offered in fundamental mode frequencies from 12MHz to 96MHz, typical production quantity lead-times are just three to four weeks.

The new vacuum sealed RFX-21 with four-pad design is offered with an operating temperature range out to -40C to 85C, an adjustment tolerance of ±20ppm at 25C and frequency stability down to ±10ppm.

Shunt capacitance C0 is 3pF max with drive levels between 0.01mW and 0.1mW. Ageing is limited to ±3ppm per year while ESR is between 30-Ohm minimum and 180-Ohm maximum. In line with the demands of the latest generation of ASICs and microprocessors, the load capacitance may be customer specified down to 8pF or Series. The new model is fully RoHS and REACH compliant.
