ceramic resistor and capacitor array strength

[Jamie Morken]

Hi,

Are ceramic resistor and capacitor networks reliable enough to use
for board design compared to other SMT components? I am wondering if
I should use them to replace multiple 0402 package resistors and
capacitors.

Digikey has parts with up to 32 resistors in 1 chip.
(search "resistor networks") and the board I am working on
has several hundred resistors so it would be nice to use them
if they are reliable for oven soldering and don't crack randomly
in the future.

cheers,
Jamie

I've used R-packs in SIP (single in-line packages), and never had a
reliability problem - I don't know why SMT would perform any less
well, unless there's a thermal problem of some kind; SIP and DIP
leads have some give - but I can't imagine multiple resistors in
a package being any worse than a pile of individual SMT resistors.

Cheers!

I am using 8 resistor pack from CTS part number 742C163473JTR. Soldered
manually never gave me any problems on about 100 boards.

The issue will be cost of parts versus the cost of assembly...

I'm agree with this, where assembly means also cost of the routing and
higher complexity than using separate parts (except if it's not a bus
terminator).
