ECS-3961 Datasheet, PDF (1/1 Pages) ECS, Inc. – SMD CLOCK OSCILLATOR

ECS-3961/3963 SERIES SMD CLOCK OSCILLATOR
The ECS-3961 (5V) and ECS-3963 (3V) is our
smallest crystal controlled low-current clock
oscillator. This subminiature, very low profile
leadless ceramic package is ideal for todays
SMD manufacturing environment. Package is
seam welded with a metal lid.
FEATURES
• 3x5 mm footprint
• SMD
• 3 & 5V versions
• Seam welded package
• Tape and Reel (1,000 pcs)
• PbFree/RoHS Compliant
