H49, 49T, H49MJ & 49TMJ CRYSTALS AT-Cut round crystal blank, optimized for low harmonics Tight tolerances and stabilities available Available <200MHz with 5th overtone mode RoHS compliant OUTLINE & DIMENSIONS DESCRIPTION H49 crystals are industry-standard crystals. Standard H49 crystals provide a very low cost source of system clock frequency while the part may also be produced with tight tolerances and stabilities. Several holder variants are available. SPECIFICATION Frequency Range H49: 1.0MHz to 1.3MHz (SL-Cut) 1.8MHz to 200.0MHz (AT-Cut) 49T: 3.1MHz to 200.0MHz Oscillation Mode: See table Load Capacitance (CL): Series or from 8pF to 32pF (Customer specified) Drive Level: 100mWatts typ., 500mWatts max. Calibration Tolerance at 25C AT-Cut: 5, 10, 20 or 30ppm SL-Cut: 50ppm Frequency Stability: See table Shunt Capacitance (C0): 7pF maximum Ageing: 2ppm maximum Storage Temperature: -50 to +105C Crystal Holder: Resistance-weld hermetic seal Supply format: Bulk pack RoHS Status: RoHS Compliant ESR and OSCILLATION MODE Frequency Holder Crystal Cut/ ESR Range MHz Type Oscill.
