± 50 PPM is standard, but tighter tolerances also available for
certain frequencies.
± 50 PPM is standard, but tighter tolerances also available for certain
operating temperature ranges.
0 - 70°C is standard, but can be extended to -40 - +85°C for certain
frequencies (just add ‘E’ after model number).
10 pF - ∞ pF (∞ pF means Series Resonance). To be specified by customer.
See table on next page.
50µW is standard, but customer may specify different drive level
± 5 PPM per year
7 pF maximum
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).

PART NUMBERING GUIDE:
n The Pletronics part number for an LP crystal consists of the following 4 elements:
1. Model Number: LP49, LP24, or LP21
2. Load Capacitance:
When the load required is ∞ pF, that is, the calibration is at series resonance:
LP49-SR, LP24-SR, or LP21-SR;
When the load required is XX pF: LP49-XX, LP24-XX, or LP21-XX.
3. Optional 3^rd Lead from the Base (Case Grounded):
3LP49
4. Frequency of Operation in MHz
EXAMPLES: LP49-SR-10.000 MHz; LP24-18-10.000 MHz; 3LP49-20-10.000 MHz
n When customer’s requirements are non-standard, a special engineering part number will be assigned.
