Effect of capacitor type in an active filter circuit?
Last Edition

When considering large C , dont' consider more than ~0.33uF until you consider larger R's 1st . If OA has high input bias current that may cause Vio offset voltage, then Change 0 ohm feedback to Vin(-) to matched R  load on Vin(+) then the offset is reduced to the spec for Iio input offset current.(Iio x Req + Vio= Vio_total) x gain > = Voutput offset error



Any GOOD designer knows how to define specs before attempting to choose parts.
LEARN THIS.  by defining as much as possible the following;


Bandpass f 
Bandpass gain 
Bandpass ripple ( possible with higher than 2nd order) 
Stopband f (important breakpoint)
Stopband min attenuation.
rise time , latency or group delay
step response % overshoot and/or resonant frequency &amp; Qu
single or split supply 
input Z (optional)
max DC offset error and gain error, 
Vin CMRR requirements ( and differential impedance balance)
supply voltage , supply noise and power consumption.
group delay distortion and Q are other ways to specify some of the above characteristics.

e.g.
Here a gain of 10 for a single supply with Vcc/2 = Vref 


R2C2 product of the filter for example cannot approach the leakage Rp*C of the capacitor, otherwise unity gain no longer exists. Rp is equiv parallel leakage.

What rise time? t= 0.35/ f-3dB YOu largest R possible such that 2% * Iin*R is acceptable offset with matched R's on each OA input with 1% tolerance.


Tantalum Polymer = 0.1CV  is the DC leakage current thus 10uF @10V = 10uA =V/R 
(ref AVX)


so 0.1CV= V/R thus RC = 10 seconds for all values and voltages for Tant. polymer

Plastic , metal film PET Polyester film (polyethylene terephthalate)
T >= 1000 seconds for C> 1.0uFand > 5000 seconds (0.33~1uF) and 15000 seconds (&lt;0.33uF)


So PET caps are your best bet. with values &lt; 0.33uF and large R values. up to 15ks/0.1uF *1%error= 1.5GOhm for 150 seconds with 0.1uF as minimum but much higher is possible with DC gain error managed.

REF KEmet: R82 Series, Radial, 5 mm Lead Spacing, 

XR7 are poor C values with sensitivity to large -dC/dV unless highV rated relative to operating range. In which case NPO/COG are much more stable and accurate and low leakage but lower k so smaller C range in same size.
