Product Description

The UM1-J surface mount crystal solution features formed leads for closer board stacking.

Available over a very wide frequency range of 1.0 ~ 300MHz, the UM-1J provides a good existing design replacement solution. This crystal solution also features a choice of operating temperature ranges including industrial -40 to +85°C, a range of temperature stabilities, as good ±5ppm, and a range of available circuit conditions.

For designs where ESR value is paramount this crystal also comes with oscillation mode options, including fundamental mode (available up to 55.0MHz), 3rd overtone, 5th overtone or 7th overtone.
