Optocoupler/LED/nixie tube/photoelectric device

Optocoupler 817B

F3 red emerald green haze common anode (Iv=R:300-700/G:2000-4000mcd(Typ)@IF=20mA)

Meihua Electronics LED SMD patch 0603 emits light from the top, yellow foggy colloid, bright white light, voltage VF: 2.6-3.1V@5mA, brightness Iv: 228-450mcd@5mA, coordinates x: 0.3, y: 0.3, light emitting Angle: 120deg

φ3 round head red hair red light emitting tube

The MCT9001 optocoupler has two channels for density applications. For quad-channel applications, two encapsulations are used to accommodate standard 16-pin DIP sockets. Each channel is an NPN silicon planar phototransistor optically coupled to a gallium arsenide light-emitting diode.
