This may work with the Mac Mini but I wouldn't suggest it. This one is actually slower than what ships with the new machine. Do a search in Amazon for "8GB 1600MHz DDR3 sodimm" I bought the Corsair Vengeance series. That's what I recommend for the 2012 Mac Mini's.
I suggest you go to Crucial's web site and use their tools (memory finder) and they (Crucial) will be able to confirm that this memory is indeed right or wrong for your Mac. I hope this helps you. Buy it from Amazon though for the best price!
The Ram I bought from Crucial for my iMac 2011 is slower (PC3-10600 1333MHz) than what is currently used for the Mac Mini 2012. The 2012 Mac Mini uses PC3-12800 1600MHz So-DIMM 204 Pin RAM. I would not recommend using slower ram in your new mac mini, you would only regret wasting your money. OWC has an 8GB Kit (4GB+4GB) for $49.99 currently and you can pay through amazon. But I would check around, as you may/possibly get it cheaper directly on Amazon.
Based on what Apple has to say, the PC3-10600 does not seem to be the correct type of memory for the 2012 Mac Mini. Per the Apple website, what you need is the PC3-12800 DDR3 204-pin SO-DIMMs (Small Outline DIMM) Use this link to see the full article: http://support.apple.com/kb/HT5475?viewlocale=en_US&locale=en_US
