Manufacturing Details
Reflow Process
Preheating: 170°C±10°C for1 to 2 minutes.
Maximum reflow: 250°C±10°C for10secs.
A DC-cut capacitor is not built in to the oscillator; a 1000pF
DC-cut capacitor is therefore required in the output line.
RoHS Terminations
AuNi
RoHS Reflow Temp
Maximum reflow: 250°C±10°C for10secs.
