TO-300

Product catalog summary

Specification
The TO-300 series includes models TO-301, TO-302, TO-311, and TO-312, with a frequency range of 10.00 to 40.00 MHz. The nominal frequency tolerance is less than +3 ppm, with stability in the temperature range of -20°C to +70°C varying between <+1 ppm and <+2 ppm depending on the model. Frequency stability against supply voltage and load changes is <+1 ppm. Aging at 25°C is +2 ppm for the first year and +1 ppm for subsequent years. Frequency correction is possible by internal trimmer (±5 ppm) or external voltage (±8 ppm). The supply voltage is 5 V ± 5%, with current consumption under 5 mA. Output is sinusoidal with a load of 560 Ohm and level >500 mVpp. Phase noise is -105 dBc/Hz at 100 Hz and -120 dBc/Hz at 1000 Hz. Operating temperature range is -20°C to +70°C, operable range is -25°C to +75°C, and storage range is -40°C to +85°C.

Environmental Conditions
The product complies with the KVG Product Qualification Procedure AA-QM-200.

Marking
Products are marked with the manufacturer's name, date code (week/year), specification, and center frequency.

Case
The case style is BF-100. Pin configurations differ between models: TO-301/TO-302 have pins for N.C., ground/case, RF-output, and supply voltage; TO-311/TO-312 include control voltage Uc, ground/case, RF-output, and supply voltage.
