X6A
SM42, SM30
LP49 CRYSTALS MOUNTED ON SURFACE MOUNT PLATFORM (HC-49/SM)
SM42 (4.4 mm high), SM30 (3.3 mm high)
STANDARD SPECIFICATIONS:
Frequency Range
3.1875 MHz - 72.000 MHz (Consult factory for specific available frequencies)
Fundamental (AT-cut)
3rd overtone (AT-cut)
Oscillation Modes
3.1875 - 30.000 MHz
27.000 - 72.000 MHz
Calibration Frequency Tolerance
at 25
°°C
± 50 PPM is standard, but tighter tolerances also available for
certain frequencies.
Frequency Stability over Operating
Temperature range
± 50 PPM is standard, but tighter tolerances also available for certain
operating temperature ranges.
Operating Temperature Range
0 - 70
°C is standard, but can be extended to -40 - +85°C (just add ‘E’ after
model number)
Load Capacitance
10 pF -
∞ pF (∞ pF means Series Resonance). To be specified by customer.
Equivalent Series Resistance (ESR)
See table on the next page.
Drive Level
50
W is standard, but customer may specify different drive level
Aging at 25
°°C
± 5 PPM per year.
Shunt Capacitance
7 pF maximum
Pullability
May be specified by customer in terms of frequency shift required over a
certain range of load capacitance, (e.g.+100 PPM from CL=12 to CL=18 pF)
This requirement may be expressed also in terms of motional capacitance
in fanto-Farad (fF).
Packaging (see page R1, Figure 2)
24 mm tape, 330 mm reel: 1000 parts per reel
PART NUMBERING GUIDE:
n
n The Pletronics part number for an SM crystal consists of the following 3 elements:
1.
Model Number: SM42, or SM30
2.
Load Capacitance:
When the load required is
∞ pF, that is, the calibration is at series resonance:
SM42-SR or SM30-SR;
When the load required is XX pF: SM42-XX or SM30.
3.
Frequency of Operation in MHz
EXAMPLE: SM42-SR-10.000 MHz, SM42-18-10.000 MHz, SM30-20-10.000 MHz
n
n When customer’s requirements are non-standard, a special engineering part number will be assigned.
