Of 20 years ago, light blue plastic cylinders 15mm long 6mm diameter,
radial
format.
With numbers like 22 GY 2 and 390 JY 2 (sic) on them for 22pF and 390pF so
large for their size . But what would number 4257 GY 2 mean , in same
package. And as standardised package, what sort of voltages, no info that
I
can find on lcrcapacitors.co.uk. I removed and measured a couple of them
but
the 4257 is in an awkward place. Another one is marked 1206 GY 2 , again
any
ideas?



Too logical for me
4257 stands for 4257 pF
Ended up removing one , so E12 series presumably +/-10% and specials
+/-0.01% in the same package and same GY 2 type designation
