Soldering Process

See solder profile on page 2.

Wash

Ultrasonic cleaning is not recommended

Notes:

1) Initial calibration @ 25°C

2) Frequency vs. temperature stability, peak to peak, -40 to 85°C.

3) Inclusive of calibration, operating tem perature range, supply voltage change, shock and

vibration and aging (20 years).

4) Specifications at time of shipm ent after 48 hours of operation.

5) Measured @ 25°C, within 5 minutes, the unit will be within +/-0.1ppm of its reference

frequency, measured after 30 m inutes of continuous operation at a stab le 25°C.
