ECS-3951M/3953M Series SMD Clock Oscillators

ECS-3951M/3953M Series SMD Clock Oscillators are miniature, crystal-controlled, low-current clock oscillators in a ceramic SMD package seam welded with a metal lid. These clock oscillators feature a 1MHz to 125MHz wide operating frequency range and low power consumption. The ECS-3951M/3953M series clock oscillators operate within the -10°C to 70°C temperature range and are RoHS-compliant and Lead-free.
