CX16 TF CRYSTAL 32.768kHz Low Profile, Ultra-Miniature Surface Mount Quartz Crystal description When miniaturization is paramount, IQD Statek's low profile CX16 TF quartz crystal is an excellent choice. Available in a frequency of 32.768kHz, this crystal has a typical footprint of 2.0 mm x 1.2 mm, and a typical height of 0.4 mm. The resonator is manufactured using Statek's photolithographic and chemical milling processes and then sealed within a ceramic package for high stability and low ageing. Available with tight calibration tolerances and high stability over temperature, this crystal is well suited for applications that have a space restraint and require a crystal with a low profile. ceramic lid PACKAGE DIMENSIONS features Ultra-miniature, surface mount design Ultra-low profile Hermetically sealed ceramic package High shock and vibration survival DIM A B C D Excellent ageing characteristics Full military testing available Applications TYPICAL inches 0.079 0.047 0.017 0.025 mm 2.00 1.20 0.42 0.64 Medical Main Clock/Real-Time Clock in: Pacemakers Defibrillators Neurostimulators Infusion Pumps Cochlear Implants Glucose Monitoring Systems Catheter Tips Surgical Instruments Spinal Nerve Stimulation and Treatment Implants IQD Frequency Products Ltd, Station Road, Crewkerne, Somerset, TA18 8AR, United Kingdom Tel: +44 (0) 1460 270200; Fax: +44 (0) 1460 72578; Email: info@iqdfrequencyproducts.com Web: www.iqdstatek.com An IQD Group Company Issue 1: 26th April 2011 (Statek Ref 10198 RevA) specifications Equivalent circuit Specifications are typical at 25 C unless otherwise noted.
