[sdiy] 0805 resistors with consistent 3 or 4 digit value markings?

Resistors are without marking in the store photos because they use the same photo for every value and don't want to confuse people. I have never encountered 0805 resistor without marking in 20 years.

There's a range of 0805 resistors at element14 manufactured by Yageo  (Phycomp).  For instance the 1% "RC0805FR-07560RL" (9237461).  As best I  understand the datasheet:     www.farnell.com www.farnell.com   these all should be marked with four digits, but the 39k  (RC0805FR-0739KL = 9237828) is simply black.  Likewise the 220k  (RC0805FR-07220KL = 9237917). The 390k (RC0805FR-07390KL = 9237941) is  marked "E06E".   I had a quick look at Mouser, but there were a plethora of resistor  types, some quite expensive and many of which were illustrated as not  being marked.  The illustrations and apparently the data sheets can't be  trusted anyway.   Its bad enough having anonymous ceramic capacitors and diodes (Diodes  Inc at least) with the polarity line only visible with a magnifier.  Vishay 1N4148Ws have a clearly visible laser-marked cathode line.  Ideally all the resistors I use would have relatively large 3 digit  value text.   I bought a Chinese-made book of 0805 resistors and a few capacitors from  eBay a few years ago.  The resistors are all 5% Yageo and are marked  clearly with three digits.  However, the range is more per decade than  E12, and misses out on several of the E12 values.  Looking again at  eBay, I couldn't find any resistor books where the range of values was  specified properly and where resistor marking was also specified.   A book would be good, but an actual range of resistors I can order on  tape in any quantity would be best.   - Robin    Daylesford Victoria Australia  ______________________________  Synth-diy mailing list   Synth-diy at synth-diy.org  synth-diy.org synth-diy.org
