The UM-1 is supplied in bulk. 200 pcs per bag is the standard bag size for this product.

Product Description

The UM-1 is a leaded crystal solution ideal for replacement or existing design projects, featuring robust leaded package with 8.00mm height.

Available over a wide frequency range from 1.0 ~ 300MHz, the UM-1 is also available in a choice of operating temperature ranges, including industrial operating temperature range of -40 to +85°C, and with a range of temperature stabilities, including very tight stability of ±5ppm. 

For deisgns where ESR value is paramount, the UM-1 offers a choice of oscillattion mode, including fundamental, 3rd overtone, 5th overtone and 7th overtone. Circuit condition can also be configured from a range of possible options.
