Their last lot sold out in less than a day. I got an order in, woohoo!

    You are going to have to post a picture of your purchase, I certainly would like to see these precision high dollar components.

    I plan to do more than that! These packs are supposedly precision resistors. Well, the company I work for happens to have a $40,000 testing machine one of whose functions is to test precision resistors. So when they arrive I'll have the test guy take a couple of them for a spin :-)

    This lot doesn't seem to have sold out yet; perhaps resistors aren't as sexy as nuts and bolts. It's an interesting lot; most of them are for terrestrial satellites, though some of those are GEO, and Mars Observer is in the mix because it was built on the same "bus" as those earth sats. Of course Mars Observer didn't get to do much observing of Mars, since it failed shortly before orbital insertion and whatever's left of it is probably in heliocentric orbit now.

    I got my order from Electronics Goldmine with some surplus NASA parts. Here's what's in it:
    Date	        Project	        Mfr	                Part	Part detail
10/10/1989	Mars Observer	Vishay Precision Group  18612	RNC90Y 2K0500 FR 
7/24/1990	Landsat					        8839 / H / 1781 / FSCJ
10/22/1990	Telestar					91637 / 943J / 1501 / FSCJ
11/6/1990	Telestar	Vishay Precision Group  RLR07	RESISTOR, METAL FILM, 0.25W, 1; 2%, 100ppm, 1ohm - 10000000ohm, THROUGH HOLE MOUNT
1/14/1991	n/a					        91637 / 805J / 5622 / FSCJ
1/29/1991	n/a					        91637 / 848J / 2050 / FSCJ
2/20/1991	n/a					        RNC55 / 8914H / 6341 / BSCJ
5/30/1991	Telestar	BSCJ				D / 120H / 3093 / BSCJ
10/3/1991	n/a					        RNC55 / 9026J / 1182 / DSCJ / P
8/1/1993	n/a	        Vishay Precision Group	18612	RNC90Y 2K0000 VR (2K)

    Can anyone explain the part labelling? For example, what are "FSCJ" and "BSCJ"?

    It's kind of fun...these parts were requisitioned, paperwork was filled out, they were transferred (in one case, there is exactly one resistor in the bag), and then they sat on a shelf. Opening the bag, you pull out the staples and no one seems to have used them. I found one of the Vishay parts online, seems to be the same model, selling for about $9.00 at Mouser or a similar vendor. There are 25 of those.

    Check out this data sheet vishay.com/docs/31025/erc.pdf

    What are "BSCJ", "DSCJ" and "FSCJ"?

    B = ± 0.1 % TOLERANCE
    D = ± 0.5 % TOLERANCE
    F = ± 1 % TOLERANCE

    M = 1.0 %/1000 hours FAILURE RATE
    P = 0.1 %/1000 hours FAILURE RATE
    R = 0.01 %/1000 hours FAILURE RATE
    S = 0.001 %/1000 hours FAILURE RATE

    C is specifying the lead material

    J = JAN (Joint Army - Navy)
