ECS-1X5X 数据手册
ECS-3X8X, 2X6X, 1X5X 32.768 KHz TUNING FORK ECS tuning fork type crystals are used as a clock source in communication equipment, measuring instruments, microprocessors and other time management applications. Their low power consumption makes these crystals ideal for portable equipment. FEATURES • Cost effective • Tight tolerance • Long term stability • Excellent resistance and environmental characteristics • PbFree/RoHS Compliant PART NUMBERING GUIDE “EXAMPLE” M ANUFACTURER ECS ECS ECS – – – FREQUENCY .327 .327 .327 – – – LOAD CAPACITANCE 12.5 12.5 8 – – – PACKAGE TYPE* 8X 13X 14X * Package type examples (8X=3x8, 13X=2x6, 14X=1x5) OPERATING CONDITIONS/ELECTRICAL CHARACTERISTICS PARAMETERS NOMINAL FREQUENCY FREQUENCY TOLERANCE LOAD CAPACITANCE (typ.)

If excessive drive is applied, irregular oscillation or quartz element fractures may occur. To determine frequency stability, use parabolic curvature. For example: What is the stability at 45˚C? 1) Change in T (˚C) 2) Change in frequency = 45 -25 = 20˚C = -0.04 PPM x (Δ T) 2 = -0.04 PPM x (20) 2 = -16.0 PPM 5.1 Max. 4.3 Figure 3) ECS-1X5X ECS, INC.
