I'm trying to source a few 0.125W 1% 1K/10K resistors but can't find
them locally (Newcastle) and it looks like paying in excess of a

tight, by all means. Can anyone help or suggest where to look locally?

is where mine came from. Cant remember the delivery charge though

if you get a bag of 100x 5% you should have no problem finding lots of
those within your 1% margin. Tempco won't be as good, so not always
suitable, but often is.


... but all the 1% and 2% will have already been sorted and taken out - so
no chance!

I'm pretty sure they're not made like that anymore.

Back in the days of E6 (20%) and E12 (10%), they were made with fairly
random values but as the tolerance of each ran into the tolerance of
the next in the series, they could just be sorted on value, and every
resistor fitted one value within tolerance.

Nowadays, all the resistors I buy seem to be 2%, which is the E96 series.
However, most suppliers still supply only E24 values, albeit still at 2%.
This means the are large gaps between valid values of 2% resistors in
the E24 series (not worked it out, but if you take random values, I
suspect somewhere around 75% of them will be invalid E24 2% resistors).

However, resistors aren't just crude carbon rods anymore. They are made
to have the required values, and can be laser tuned during manufacture.
I suspect if you bought a bag (or bandolier) of 100x 5%, you'd be more
likely to find they all +3.55%, or some such.
