ACT HC49/U ( Standard Devices )
The ACT HC49U family is available in industry standard package and specifications. 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 )
