UM1 & 5
The ACT UM1 & UM5 family are available in industry standard package & specifications. The series offers a
broad range of frequencies and tolerances in both standard and industrial temperature ranges. Housed in
resistance welded cases the UM1 & 5 now have improved aging characteristics. These devices are
particularly popular in Pager, Wireless Telemetry, Wireless Lan and UHF / VHF Radio applications.There is
a gull winged option (with mounting clip) available for lower profile ("SMD" ) mounting.
