Surface mount crystals
Frequency control specialist 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 suitable for use in miniaturised hand held equipment such as PDAs, GPS, PCMCIA and similar high density applications where space is at a premium.
Offering low aging 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.
