Datasheet

Euroquartz has announced the release of its latest ultra-miniature AT-cut crystals covering the frequency range 16 to 60MHz in fundamental mode. The new X22 crystals are housed in a microminiature 2.5 x 2.0 x 0.6mm surface mount package making them ideal for use in miniaturised hand-held equipment such as PDAs, GPS, PCMCIA and similar high density applications where space is at a premium.

Offering very low ageing of less than ±2ppm per year at 25°C, specifications include calibration tolerance at 25°C of ±10ppm, ±20ppm and ±30ppm and frequency stability of ±10ppm from -10 to +60°C (±5ppm available), ±10ppm from -20 to +70°C and ±15ppm from -40 to +85°C. Drive level is 50 to 100μW maximum while shunt capacitance is 2 to 4pF typical, 5pF maximum with load capacitance series or from 9 to 32pF. Storage temperature range is -50 to +105°C.

Supplied on standard EIA tape and reel, the new X22 crystals are capable of withstanding reflow soldering conditions of 260°C for 10s maximum (twice) or 230°C for 180s once.

Euroquartz is an independent UK-based manufacturer and supplier of quartz crystals, oscillators, filters and frequency-related products to the electronics manufacturing industry worldwide. The company designs and manufactures a comprehensive range of frequency control components for a wide range of customers including major OEMs in a broad spectrum of applications including military and aerospace, communications, general electronics, computing, control systems and petrochemical among many others.
