| THROUGH-HOLE CRYSTALS HC35 CRYSTALS (TO5) DESCRIPTION HC35 crystals are used in communications, aerospace and defence applications The crystal blank used in HC35 packages is capable of being manufactured to close tolerances and is readily produced with custom frequencies and specifications. OUTLINES AND DIMENSIONS 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 25C: Frequency stability over temp: Operating Temperature Range: Shunt Capacitance (C0): Load Capacitance (CL): Motional Capacitance (C1): Effective Series Resistance: Ageing: Drive level: Shock: Vibration: Holder: Supply format: 8.0MHz to 250MHz See table from 3ppm from 3ppm (see table) From 0~+50 to -55~+125C 4pF maximum (See table) Series or from 8pF to 32pF (Customer specified CL) See table See table 2ppm max 1st year, 1ppm typical per year after 100uW maximum 100g/6ms 10g/1.5mm, 10~500Hz, 3 axis Resistance-weld, hermetic seal Bulk pack FREQUENCY STABILITY OVER TEMPERATURE Operating Temp.
