"_" is voltage code. For RoHS equivalent model please add "G" after the package code. M14TG3, for example, would be a Voltage Code "3" RoHS-compliant S series M14 package.

(1) MW57T, VM57T, M53T, and VM53T are RoHS compliant and lead-free products.

Note: Frequency tuning by built-in mechanical trimmer (variable capacitor) is standard for all models except models M57T, VM57T, M53T, and VM53T. Please specify when ordering if trimmer is not required.

Note: Non-hermetically sealed (VC)TCXO products are not subjected to the washing cycles as the solvent degrade the trimmer capacitor. If cleaning is mandatory please choose hermetically sealed packages or no-trimmer option.

Note 1: Some specifications are package dependent. Please refer to the spec. sheet of individual packages once a package is selected..
Note 2: TCXO products ordered without mechanical and electrical frequency tuning should have a frequency tolerance of ±2 ppm (at +25°C) and the frequency stability over temperature will be from that measured value.
