ECS-.400-12.5-8 数据手册
ECS-31 SERIES LOW FREQUENCY QUARTZ CRYSTALS The ECS-31 Series features the same characteristics as only tuning fork crystals offer. Because of their miniature size they are ideal for portable and communication equipment applications. FEATURES • Miniature size • Cost effective • Long term stability • Excellent shock and vibration characteristics PART NUMBERING GUIDE “EXAMPLE” MANUFACTURER ECS ECS ECS – – – FREQUENCY .400 .400 2.0 – – – LOAD CAPACITANCE 12.5 12.5 12.5 – – – PACKAGE TYPE* 8 13 14 * Package type examples (8=3x8, 13=2x6, 14=1x5) OPERATING CONDITIONS/ELECTRICAL CHARACTERISTICS PARAMETERS FREQUENCY RANGE FREQUENCY TOLERANCE FREQUENCY VS.
