Quartz Crystal Specifications
To ensure that all products supplied are to the customers requirements it is important that all the relevant information is supplied when a purchase order is placed.
AEL use two methods to correctly specify parts. First is an AEL Crystals specific part number which can be quoted, in addition an industry standard “short-code” is used.
The AEL part number is structured as follows
X 12M123456 L 001
Product Type
X = Crystal
O = Oscillator
C = Ceramic Resonator
F = Filter
V = VCXO or VC-TCXO
T = TCXO
S = SAW Device
Q = OCXO
D = Dielectric Resonator
A = Antenna
M = MEMS Oscillator
Frequency
L = Thru-Hole
S = SMD
Sequential stock-code
The industry standard short-code shows the minimum amount of information that AEL Crystals would need to have in order to commence manufacture of this part. Additional information may be required for certain applications, please discuss this with one of our technical staff who will be able to advise you on any specific requirements.
