This series offers a broad range of frequencies and tolerances in both standard and industrial temperature ranges. Housed in resistance welded cases the HC49U offers excellent aging characteristics. Cost / performance ratios are extremely good for this family of devices and they offer reasonably high density mounting capability, where height isn't a restriction. Low frequencies are also more readily available in this type of package. Various optional packages and custom specifications are available - PLEASE SEE SEPARATE DATA SHEET FOR ACT HC49/U ( CUSTOM OPTIONS ) Symbol Condition Customer to specify : Frequency, Frequency Tolerance, Temperature Stability, Operating Temperature Range, Load Capacitance & Mode In line with our ongoing policy of product evolvement and improvement, the above specification may be subject to change without notice 500M Ω Min 6.000 ~ 6.999 30.000 ~ 65.000 60.000 ~ 99.999 90.000 ~ 120.000 120.000 ~ 150.000 -10 ~ +60°C -20 ~ +70°C -40 ~ +85°C ±10ppm ±15ppm ±20ppm ±25ppm Enquire ±30ppm ±50ppm Stability Temp |
