Tantalum capacitors in parallel?

Hi

No Problem should be occur if you use same value and type . As the value and type of capacitor changes ; their parasitic effect also changes , If you use different type/value of capacitors in parallel then it might create resonant tank effect which will increase the total ESR. and if you use same value/type of capacitors in parallel rather using just one then it would be having less total ESR then that Single one. Just the Space would be a trade off ! ...
