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?
