THROUGH-HOLE CRYSTALS UM-1SL SLIMLINE CRYSTALS OUTLINES AND DIMENSIONS DESCRIPTION UM-1 Slimline crystals are popular for communications applications such as pagers where their small size and slimline profile is easily incorporated into equipment designs. The crystal blank used in this package is capable of being manufactured to close tolerances and is readily produced with custom frequencies and specifications. FEATURES · · · · · Wide frequency range Small profile, low-mass package Close tolerances easily achieved Fully customisable specification Industry-standard package GENERAL SPECIFICATION Frequency Range: Oscillation Mode: Calibration Tolerance at 25ºC: Frequency stability over temp: Operating Temperature Range: Shunt Capacitance (C0): Load Capacitance (CL): Effective Series Resistance: Ageing: Drive level: Holder: Supply format: 8.0MHz to 200MHz See table from ±3ppm from ±2.5ppm -10° to +60°C From 0°~+50° to -55°~+105°C 4pF typical, 7pF maximum Series or from 8pF to 32pF (Customer to specify CL) See table ±2ppm max 1st year, ±1ppm max per year after 100mW maximum Resistance-weld, hermetic seal Bulk pack FREQUENCY STABILITY OVER TEMPERATURE Temperature Stability (ppm) Operating Temp. °C ±2.5 ±5 ±7.5 ±10 ±15 ±20 ±30 0° to +50° ü ü ü ü ü ü ü -10° to +60° ü ü ü ü ü ü ü -20° to +70° X ü ü ü ü ü ü -30° to +80° X X X ü ü ü ü -40° to +90° X X X X ü ü ü -55° to +105° X X X X X ü ü PART NUMBER GENERATION UM-1SL crystal part numbers are derived as follows: OSCILLATION MODE & ESR Frequency (MHz) Crystal Cut Osc.
