Questions you mayask
1.what''s the gengeral lead-timeof the products?
| product | lead time |
| HC49 SERIES | 1~2weeks |
| SMD Crystal | 1~4weeks |
| DIP Oscillator | 1~2weeks |
| SMD Oscillator | 1~3weeks |
| TCXO | 2~8weeks |
| Watck crystal | 1~2weeks |
(*Exact delivery is subject to WTL firm reply to each order.Fornormal frequencyed, we have safety sock)
2. Since thelead-time is set, what about sampling?
Usually the samples are need thesame lead time, By the way, we can offer each customer 10~20 pcssamples free of charge.
3.What basicinformation to provide when ordering acrystal?
Generally we request the customerto provide the centerl frequency, type of cutting angle(AT/BT),holder or packing type, resistance(ESR), frequency tolerance,frequency stability, load capacitance, operating temperature range,drive power, aging, etc, Customer can also specify other specificspec or requirement, if any, when placing orders.
