Component Identification

[Tim]

Hi,

Could anyone help me properly identify this component please ? I'm
half guessing - it's a resistor network with 6-resistors at 10Mohms
each. Thin film maybe ? Can't seem to find a source of them though ?
Any clues ?

Cheers.

It would be useful to have an image that is less than 2.1mb......

Based on the outline of 6 separate resistor blocks on the PWB, it sure
looks like 6 isolated 10 M resistors.

FST is either a brand marker, or it could be the tolerance,
reliability, and tempco, etc. markings.
F usually means 1% for the parts that I am used to using.
S usually means a failure rate of 1 per million hours.
T is unknown, but it also may call out the lead coating (tin?)

You could also use a nice browser like Firefox that auto zooms.

Got it, but the default browser is Opera 9.5.

Resistor networks with values much bigger than 100K simply aren't that
common in the wide world.

Are they put on thin film for matching, etc? If not, 6 individual 10M
resistors aren't that expensive...

Are you trying to continue support of an older product, clone somebody
else's product, ???

To me that looks like a "thick film hybrid", which is device that is made by
screen printing the conductors onto a ceramic substrate. The blue potting
plastic is a protective covering for the printed resistors.

You could verify exactly what the circuit is by desoldering the component
from the board and measuring it with a multimeter.

As one of the other posters mentioned, it is likely done for precisely
matching the resistors. It could well be a "custom made component", so
finding a replacement may be difficult.

It doesn't appear to be very small, so replacement with single matched 10M
resistors may be possible.

cut one leg close to the PCB to isolate the component, and measure to
see if it is a 10meg resistor. If it isn't, solder the leg back. It
isn't a resistor network.

If it is 10Meg, try another leg, and measure again. It it comes up the
same, you can repeat this procedure, or simply solder a 10Meg resistor
across the open bridge(s) to check circuit operation.

good luck.

Cheers Don...
