Crystal Resonators
UM-1, UM-4, UM-5, HC-49/T, HC-49/U, HC-50/T, HC-50/U
The UM Series Resonators feature excellent frequency stability and are
suitable for pager and mobile radio applications. These highly impact-
resistant, reliable crystal resonators have been reduced in size without
trading off their electrical characteristics.
The HC Series Resonators are excellent in frequency stability and suit-
able as the reference clocks of microprocessors and other electronic
devices.
Features
Automatic mounting with tape & reel form is possible.
