Microphonic film capacitor

The most microphonic caps I've ever met were poorly manufactured electrolytics. The 'capacitor pill' wasn't securely located in the can. The re-work that involved ! Thanks purchasing.

Then there was the batch of TL072s the MD insisted on buying cheap ( they'd been soaked in a leaky container during shipping ). LMAO. What the guys behind desks do is something else.

Funny thing though is surface mount resistors measure as about the most ideal resistor you could imagine. The ESL is just the electrical length.

I can see through-hole parts have less microphonics since the lead itself relieves stress on the part.

Generally the guys behind the desk sink the company, but make sure they have a golden parachute.

Sadly the surface mount resistive film has more excess noise than metal film leaded. You can HEAR the difference. The material used is grossly inferior. It's even on the data sheets where the manufacturer dains to publish the numbers.

Plus, the dielectric films used in SMT caps and the construction don't match what we audio pros are used to.

Time for change. Politics and dumb politicians are no different. I LOATHE most of them. There a FEW good 'uns though, bless them.

I don't doubt the differences. My point is strictly on parasitics. The chip resistors measure well.

Thanks; i can dig that out if i need it. Always thught glass caps were cool...

Depends on the brand and type..witness those old Sprague caps!

Well my reading on that is that it would damage the interests of the real big money types. I have a better idea, get rid of the tortured tax laws that help create megacorporations that cannot be brought to account for their deeds.
