Questions you may ask about our crystal filter 10.7mhz (MCF)
1.what's the gengeral lead-time of 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.For normal frequencyed,we have safety sock)
2. Since the lead-time is set,what about sampling?
Usually the samples are need the same lead time,By the way,we can offer each customer 10~20 pcs samples free of charge.
3.What basic information to provide when ordering a crystal?
Generally we request the customer to 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 specific spec or requirement,if any,when placing orders.
