òîòó. Body clearances: diameter 2ìì, length 6ìì.
Descrição porminorizada da marca:Nominal frequency of Fn. From 32000 to 36000 Hz;
tuning accuracy of dF/Fí. +/- 50 ððì;
dynamic resistance of Rê. 95 lumps;
static capacitance of Ñ0. 1, 3 +/- 0, 2 pension funds;
capacitance coefficient of Ñ0/Ñ1. 870 +/- 00;
capacity, scattering on resonator of W. 1 microWatt;
resonator ageing for first year of storage of dF/Fí. +/- 5 ððì;
time constant of thermal inertia in fluid t. 5 secs;
temperature-frequency characteristic (Ò×Õ):
FT = F0 + A1 ( t - T0) + A2 (t - T0) ^2 + A3 (t - T0) ^3,
where: FT - resonator frequency (Hz) in case of running value of temperature
t (ãðàäÑ); F0 - resonator frequency (Hz) in case of base significance
t temperature (hail c); Ò0 - basic value of temperature.
to get great accuracy possibly Ò×Õ presentation polunomial

the resonators are products unrestorable and repair not
are subject to. The maker guarantees the adequacy in quality of resonator
in case of observance by the conditions consumer of transportation, storage and
operation. Guarantee period - 50000 ch from the day of input
resonators in operation. Guarantee storage life - ten years with
time manufacture. Maximal relative frequency variation
