micro-miniture IC protector letter codes?

[N_Cook]

Just for future reference , not blown , but anyone know the full series /
letter rating , assuming some sort of standard
1.5mm long SMD, with letter G , measures 1.6R
and one marked P is 1.2R
the letters P and G are marked in large letters next to the otherwise
unlabelled devices on the overlay.

As in Panasonic kit , perhaps these 1x .5mm SMD , with solder over probably
looks more like 1.5mm, The ones before me the ceramic core is light blue
colour, maybe relevant
