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.
