Use of tantalum capacitors with MAX232

[pratyathedon]

I want to know that what is the use of tantalum capacitors with max232
why we not use normal electrolytic capacitors.
Thanks in advance

hi,

You can use most types of electro capactitors with the Max232 chip, its just that the Tantalum ones have better performance - primarily their low leakage.
The downside is their cost in standard size components.
See Wiki for full details.

Yes..you can use eletrolytics with MAX232 which will work without problems. But for better stability and accuracy, tantalums are too prefered. It is not mandatory in any wayto use tantalums only. I have even used 104 disc capacitors which work well even today since 5-6 years. Cheers

Nowadays, the difference in cost between aluminium and tantalum capacitors of the size needed there is not worth the time you spend thinking of it.
