well actually a good tradeoff between tantalum and ceramic capacitors is another family of capacitors called polypropylene capacitors which were previously costlier but nowadays are quite cheap (well .... cheaper than tantalum ). these capacitors are usually the next best aternatives for ceramic caps and the regular ones available can have a value upto 1uF. these capacitors have excellent long term reliability/stability and are preferred in analog circuits using integration/differentiation,RC oscillaters,succesive approximation ADCs...etc

Yeah and they're indispensable in audio ckts as well,esp in the signal path(where tants,electros and even ceramics suck big time).

Hi Amit, don't get confused, for the 0.1 or 104 we regularly use by the VCC pin, use conformally coated radial capacitors (small yellow mainly). They are basically ceramic, also known as multilayer ceramic capacitors. They have very good temp stability, and are normally 10% tol, temp range -55 to +125deg C, dielectric X7R(?) and Z5U(?). As pdi said, bit costlier than ceramic disc, but much cheaper than tant. :-)
It feels good to give gayaan
:bye

Does anyone have microcontroller programming software for STC15F104W (core 8051, 4 k, 128 byte, 6 I/O pin, UART ... DIL8), that works?

Hi I am looking for a assembly language program for a digital decimal counter. Time counts max limit of 2 mins starting from 2.00 mins and ending at 0.00. time is to be displayed on 4 7-segment LED displays. Edsim51 simulator to be used. Thanks
