ECS-8F
SERIES
SMD CLOCK OSCILLATOR
The ECS-8FM (5V) and ECS-8FA3 (3.3V)
CMOS compatible, J-leaded SMD oscillator.
The 8F series utilizes a low power CMOS IC
in a cost effective package suitable for reflow
soldering.
FEATURES
• 5.0V & 3.3V versions
• Extended temperature range
• Tri-State function
• Tape and Reel (1,000 pcs STD)
