For those of you having a hard time sourcing the MELF resistors, JPS64 said that he will provide a set to make two SMT daughterboards for 3 Euro. He did check with Mouser (USA) to verify that they were in stock before he finalized the layout. There must have been a big project somewhere in the US that wiped out all the stock. Send JPS64 a PM if you would like a set. Or perhaps we can start a MELF resistor GB list here even.

Metal Electrode Leadless Face (MELF) resistors, because they are round and can roll or eject off the end of a tweezer, they are also known as Most End up Lying on the Floor...

KOA SPEER makes them too. I suppose in the future 0805 pads would be useful as it allows either low cost easy to find chip or MMU (0102) MELF to be used.

From Wikipedia, advantages of MELF:

Quote:
Despite their handling difficulties, and in the particular case of MELF resistors, they are still widely used in high-reliability and precision applications where their predictable characteristics (e.g., low failure rate with well-defined failure modes) as well as their higher performance in terms of accuracy, long-term stability, moisture resistance, high-temperature operation far outweigh their disadvantages.

GB for MELF resistor kit (set) by JPS64. 1 set is enough for making a pair of SMT daughterboards. 3 Euro per set.
