I want to buy some 0402 SMD capacitors (well some is about 1 to 10k).
I always use the method of use the cheapest part for the given specs
approach. But today I noticed something odd:
I was comparing these two parts on digikey:
Partno. Price/piece Price for 10k
-------------------------------------------
490-10777-2-ND 0,00317€ 31,68€
399-8942-2-ND 0,08236€ 823,63€
The top one is from a company called murata (never heard of them) and the bottom one is from KEMET (which I know of). But looking at the specs given, there is absolutely no justification for the much higher price:
I know there might be some other parameters which might come in to play which are not listed by digikey.
But really 10 times the price for some capacitors? What is the justification ? Is it because of the brand-name? If so, why should I care?
