The frequency provided by this component is stable over varying temperatures and drive levels, spanning a frequency range of 12 to 50 MHz.
The frequency tolerance is ±30 ppm by default, with options for tighter tolerances of ±10 ppm, ±15 ppm, and ±20 ppm.
Frequency stability is rated at ±50 ppm standard, with available stability options ranging from ±10 ppm up to ±40 ppm.
Designed to operate over a wide temperature range, from -20°C to +70°C in its standard version, with an extended range option from -40°C to +85°C.
Packaging adheres to the EIA-481-2 standard for tape and reel packaging, enabling automated manufacturing processes.
Compliance with RoHS/Green standards ensures the product meets current environmental safety norms.

Ordering Information

When ordering the Model 403, precise specifications need to be provided which are encoded in the part number:

Operating Temperature Range is represented by different codes like ‘C’ for the standard range (-20°C to +70°C) and ‘I’ for the extended range (-40°C to +85°C).
The Desired Frequency in MHz has five significant digits after the code “M,” indicating the specific frequency required.
Frequency Tolerance is indicated by different codes such as ‘1’ for ±10 ppm, ‘X’ for ±15 ppm, ‘2’ for ±20 ppm, and so forth, with ‘3’ being the standard.
Load Capacitance options are represented by alphabetic codes from ‘A’ to ‘S’, defining specific capacitances from 8 pF to 32 pF, as well as ‘S’ for Series.
Stability Tolerance across the operational temperature range is also indicated using codes ‘1’ through ‘5’, with ‘5’ being the standard option of ±50 ppm.

Two example part numbers illustrative of the ordering system are given: 403C35414M31818 and 403135432MO0000.
