Quick answer
OPTO PLUS LED model numbers indicate product functions. Codes reveal details like connection type (SMD or through-hole), display type (single, dual, etc.), and emitting color (yellow green, blue). The reflector version is also identified within the model number code.

We will briefly explain OPTO PLUS LED model number rules. OPTO PLUS LED model number rules will show these product functions at a glance.
