WATTS = Amps X Amps X R
eg, 0.23 x 0.23 x 4.7 = 0.248...
All above FR's are 1/4W
FR's "always" drift high, the reading on FR405 looks suspect. Was this in circuit
or with one leg lifted? Agree FR401, FR403 OK, yeah I'd replace FR409, first check
your MM leed resistance/touch probes together, less than 1 ohms? Then subtract this
from the FR409 reading. A 20% tolerance is probably just OK, so less than 6 would be
ok?
FR's are difficult for me to sources. Mouser doesn't carry the FRM25 series anymore
and has a limited select of the Vishay CMF, others??
