Initial accuracy does not include shift due to solder heat effect.
The long-term stability specification is noncumulative. The drift in subsequent 1000 hour periods is significantly lower than in the first 1000 hour period.
StartFragmentTheoretical parameter calculation:
Take C0=C1=C2=0.01uF.
Then the reference resistance R0= .
Quality factor Q=fo/BW.
When f0=500hz,Q=10,Au=4.5 .
The resistor values are:R1=QR0/Au = 70.7K ...
