EX-421

Evacuated Miniature Crystal Oscillator

EX-421

Description

The EX-421 provides exceptionally low aging rates and tight temperature stabilities in an extremely small package over a wide

range of environmental conditions. This EMXO series bridges the gap between current large, high precision OCXO’s and smaller

TCXO’s. The EX-421 Series becomes the most economical choice where there is a need for spectral purity, short and long term

stability, along with small size and dramatically reduced power consumption.

Features

Low Power Consumption Precision Oscillator

Fast Warm-up

Low Phase Noise

Good Aging

Small Form Factor

SMD and Thru-Hole Mounting Option

RoHS Compliant

Standard Frequencies: 10MHz, 20MHz and 100MHz

Design/Material Sourcing/Manufacture/Test in MHS,PA COO:USA

No ITAR Restriction for importing EAR99

Previous Model Number: EX-620, EX-420 series
