Description
Red standard 3mm light emitting diodes are a superb, high quality component requiring a series resistor.
These LEDs DO require a series resistor which is not included, but are available separately. The resistors listed below are the minimum required for safe operation.
If operating from a 9v DC supply use 270R Model Number 228-505 carbon film resistor.
If operating from a 12v DC supply use 390R Model Number 228-507 carbon film resistor.
If operating from a 16v DC supply use 560R Model Number 228-509 carbon film resistor.
Cathode or negative identified by shorter lead.
Sold individually so you only buy what you need.
