Product Details
✓Self-flashing LED with integrated flash circuit - 20 Red self-flashing LEDs with built-in flash circuit that pulse on a fixed cadence — suitable for model railroad signals, security indicators, prop electronics, and panel displays with integrated timing
✓Fast flashing at 2Hz with 8,000-10,000 mcd output - Built-in flashing IC drives the LED at 2Hz (two flashes per second) for attention-getting signal patterns. Red emission at 620-630nm wavelength through a clear lens, 1.9-2.1V forward voltage at 20mA drive current, 20-30 degree viewing angle for focused directional output.
✓Standard 5mm radial through-hole package - Two-lead DIP form factor fits standard 2.54mm pitch breadboards, perfboard, and PCB layouts. Integrated flash circuit is sealed inside the epoxy lens body, so the part installs and solders identically to a non-flashing 5mm LED with no extra components on the board.
✓Polarity and resistor reference - Through-hole LEDs are polarity-sensitive: longer lead is anode (+), shorter lead is cathode (−). For 20mA drive current with a 1.8-2.2V LED, use a series resistor of 150Ω 1/4W on 5V, 360Ω 1/4W on 9V, 510Ω 1/4W on 12V, or 680Ω 1/2W on 15V.
✓Hobby and prop applications - Suited to emergency vehicle simulation (police, fire, ambulance scale models), brake-light and stop-signal strobe effects, model railroad warning signals at crossings and rear markers, halloween prop eye glow, theatrical fire and alarm effects, and security indicator panels.
