Bi-Color Red Blue Changing Flashing Led 5mm

Bi-Color Red Blue Changing Flashing 5mm LED is a dynamic component that instantly brings attention and flair to any electronics project. Unlike standard single-color LEDs, this versatile light source houses two separate light-emitting diodes (red and blue) within a single 5mm package, along with a tiny integrated circuit (IC) that controls their flashing sequence. This built-in controller automatically cycles the LED between vibrant red and bright blue colors, creating a continuous, eye-catching visual effect without requiring any external microcontroller or complex programming. Engineers, educators, and hobbyists often choose this self-flashing LED for its simplicity, reliability, and immediate visual impact in indicators, toys, and signaling devices.

Key Features:

• Automatic Color Cycling: An integrated circuit manages the flashing sequence, automatically switching the output between red and blue without external control.
• Bi-Color Output: Offers two distinct, high-intensity colors (red and blue) from a single 5mm lens, maximizing visual presence.
• Simple Two-Pin Operation: You only need to connect power and ground—just like a standard LED—making integration effortless.
• High Visibility: The 5mm package and changing colors ensure the LED is highly noticeable, making it perfect for status indicators and alarms.
• Low Power Consumption: It operates efficiently, requiring minimal current to maintain its bright, continuous flashing pattern.

Technical Specifications:

• LED Type: Bi-Color (Red and Blue) Flashing
• LED Size: 5mm
• Forward Voltage (Vf): Typically 3.0V – 3.4V DC
• Forward Current (If): Typically 18mA – 20mA
• Wavelength (Red): ~620-630 nm
• Wavelength (Blue): ~460-470 nm
• Operating Frequency: Built-in flasher IC determines the flash rate (varies by batch, typically 0.5Hz – 1.5Hz)

Mechanical Specifications:

• Lens Type: Clear or Diffused Round Lens (depending on batch)
• Lead Material: Tin-plated, solderable leads (Anode and Cathode).
• Housing Material: Epoxy Resin.
• Seating: Standard through-hole mounting.

Dimensions:

• Diameter: 5.0 mm
• Overall Height (Lens + Base): ~8.5 mm
• Lead Length: Minimum 25 mm (typical)

Pinout and Wiring:

• Anode (+): The longer lead; connect this to the positive power supply through a current-limiting resistor.
• Cathode (-): The shorter lead; connect this to the ground (GND).
• Wiring Note: You must use a current-limiting resistor (e.g., 150-ohm to 330-ohm for a 5V supply) in series with the Anode to prevent the LED from burning out. The resistor safely drops the voltage and limits the current to the recommended level.
