| Item / Type | MJ series ( 5.0 * 3.2 * 0.9 mm ) | ||
|---|---|---|---|
| Frequency Range / Crystal Cut |
10.000 ~ 50.000 MHz , AT-cut , Fundamental Mode ( see Table 1 ) | ||
| 40.000 ~ 125.000 MHz , AT-cut , 3rd overtone ( see Table 1 ) | |||
| note: Frequencies between 40 and 50 MHz can be either AT fundamental or AT 3rd overtone. To avoid mistake, please add "AF" after the frequency on part number for AT-cut fundamental mode. "A3" for AT-cut 3rd overtone. For example: MJ-40.000AF-20P. |
