Capacitor Array?

What's the context?

I'm placing an order at dig key some of which is for an elliptic LPF.

I would like to use the arrays to make up the capacitors in the filter. The data sheets I've been looking at Digikey don't state if it's total array capacitance or each elements capacitance.

I'm searching under capacitor arrays at Digikey.Here is an example TDK data sheet.

I've alaways assumed it was specified for each element now I'm not sure.

Forgot here is where I'm searching

Under Capacitors ---> Arrays

It is amusing that in the above TDK data sheet, and the Panasoinc one at

they manage to avoid actually stating that the capacitance value is for each individual capacitor, but this does follow from the performance of the 'measurement circuit' in the Panasonic note. It's also rather likely in the case of the TDK part - in fact, much more likely than the given value being the sum of the individual values.

Why not ask Digikey?

I have some of these on hand 0.1uf 4 element array.

I soldered one into a blank PCB and measured 428nf. So it is 4 elements times the specified value.

I don't see any advantage to using the array. I can see a disadvantage in that you may need longer leads to hook up the caps.

Hello,

for resistor arrays they usually specify the value of each single resistor, especially if those are independent resistors not connected together.
