Tuning Fork Quartz Crystals Technical Data 32S12 Series 32.768 kHz Plastic SMD www.pericom.com
Description
The 32S12 Series is a micro-miniature, plastic-molded, surface mountable ver - sion of the 32.768 kHz tuning fork-type quartz crystal. The crystal is housed in a rugged, high-temperature tubular holder, then mounted to a leadframe and injection molded into its plastic carrier. Two sizes and two lead connection configurations are available. ACTUAL SIZE Applications & Features Very small, compact packaging Rugged, plastic-molded design, resistant to shock and vibration Excellent resistance to heat shock and environmental characteristics Ideally suited for automated pick-and- place assembly environments Available on tape and reel Ideal for portable applications, time of day clocks, communication equipment, pagers, cellular telephones, camcorders, and micro computers Electrical Specifications Nominal Frequency @ 25°C – F Frequency Tolerance ±20 ppm +25°C ±5°CTurnover Temperature – TO Temperature Coefficient – K (-3.5 ± 0.8) × 10-8 / °C2 50KΩ max 1.0 pF, typ 1µW max -40 to +85°C ±5 ppm, max -55 to +125°C 12.5 pF standardLoad Capacitance – CL Equivalent Series Resistance – RS Shunt Capacitance – C0 Operating Temp.
