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. See Table 2 on the next page.
0 - 70°C is standard, but can be extended to -40 - +85°C (just add ‘E’ after
model number).
Operating Temperature Range
Load Capacitance
Equivalent Series Resistance (ESR)
Drive Level
Aging at 25° C
Shunt Capacitance
8pF - ¥ pF (¥ pF means Series Resonance). To be specified by customer.
See Table 1 on the next page.
50mW is standard, but customer may specify different drive level
± 5 PPM per year is standard, but ±1 PPM also available.
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).

n
The Pletronics part number for a UM crystal consists of the following 4 elements:
1. Model Number: UM1, UM4, or UM5
2. Optional Gull Wing Package: UM1G
3. Load Capacitance:
When the load required is ¥ pF, that is, the calibration is at series resonance:
UM1-SR, UM4-SR, UM5-SR;
When the load required is XX pF: UM1-XX, UM4-XX, UM5-XX.
4. Frequency of Operation in MHz
EXAMPLES: UM1-SR-10.00 MHz; UM5-18-10.00 MHz; UM4-20-10.00 MHz; UM1G-SR-10.00 MHz
n
When customer’s requirements are non-standard, a special engineering part number will be assigned.
