The emission color of a light-emitting diode is generally the same as its own color
Main parameters of diodes
Maximum operating frequency FM: The frequency of the highest AC signal with unidirectional conductivity of a diode.
Silicon switch diode fully sealed ring epoxy resin ceramic chip package
Several aspects to consider when selecting a transistor
Use a multimeter to test. Using a pointer multimeter with a 10k Ω range can roughly determine the quality of the light-emitting diode
