DESCRIPTION
UM-1SMD and UM-5SMD crystals are standard UM-1 and UM-5 crystals with ormed leads and fitted with a clip to enable surface mounting. This offers the benefits of maintaining a highly specified crystal while facilitating surface mount assembly. 1.0 ~1.2 SL Fund. 5k 6.0 ~ 6.9 AT Fund. 100 7.0 ~ 7.9 AT Fund. 90 8.0 ~ 8.9 AT Fund. 80 9.0 ~ 10.9 AT Fund. 60 11.0 ~ 12.9 AT Fund. 40 13.0 ~ 45.0 AT Fund. 25 30.0 ~ 50.0 AT 3rd o.t. 40 50.1 ~ 100.0 AT 3rd o.t. 50 80.0 ~ 200.0 AT 5th o.t 80 FREQUENCY, OSCILLATION MODE, ESR PART NUMBER FORMAT 8.000MHz UM-1SMD/10/10/-20+70/32/ 80RExample: Frequency Range MHz ESR Max.
