0807 SMD slow-flashing LEDs pack a 1Hz self-flashing circuit into a tiny surface-mount package measuring just 2.0mm × 1.8mm × 0.8mm. The built-in integrated circuit (IC) blinks the LED once per second automatically — no microcontroller, no external timer, no code. Just solder the SMD pad to your PCB, add a current-limiting resistor, apply DC power, and the 1Hz flash begins. Surface-mount animated LEDs are designed for applications where through-hole leads are impractical: custom PCB designs, LED strip and flex circuit builds, ultra-compact wearable electronics, and production assemblies where automated pick-and-place soldering is standard. The 0807 package is the larger of our two SMD animated sizes, making it easier to hand-solder than the smaller 0603 while still being far more compact than any through-hole animated LED.

Custom PCB and production designs: Electronics engineers and PCB designers specify 0807 SMD flashing LEDs for on-board status indicators that blink without consuming a microcontroller GPIO pin or requiring any software overhead. A PCB-mounted 0807 slow-flash LED connected directly to the power rail through a resistor provides a visual “power present” blink that works even when the microcontroller is halted, crashed, or in deep sleep — an independent hardware heartbeat. Production assemblies for IoT devices, sensor nodes, and consumer electronics use SMD flashing LEDs for factory test indicators and shipping-mode visual confirmation lights. The 0807 package is compatible with standard reflow soldering processes and pick-and-place equipment.

LED strip and flex circuit builds: Custom LED strip designers and flexible PCB builders use 0807 SMD flashing LEDs to add blinking segments to otherwise static strips. A strip with alternating static and flashing 0807 LEDs creates an eye-catching mixed pattern without any external controller IC. Wearable tech designers solder 0807 flashing LEDs onto flexible Kapton-based PCBs for blinking costume accents, badge indicators, and safety wearable markers. The low-profile 0.8mm height lies flat against the flexible substrate without snagging or protruding.

Model railroad and miniature PCB applications: Advanced N scale and Z scale model railroaders who build custom PCBs for locomotive and structure lighting use 0807 SMD flashing LEDs as the smallest possible animated indicator. Mounted directly on a tiny daughter board inside a locomotive shell, the 0807 provides a flashing headlight, ditch light, or marker light without requiring the microcontroller overhead of a DCC decoder function output. The SMD package has no through-hole leads to route through tight spaces — it sits flat on the PCB surface.

Available colors and specifications: We stock 0807 SMD slow-flash LEDs in red, amber, green, blue, cool white, and warm white. Forward voltage: red/amber ≈ 2.0–2.2V; blue/green/white ≈ 3.0–3.2V. Maximum current: 20mA. Package dimensions: 2.0mm × 1.8mm × 0.8mm. A current-limiting resistor is required (an 0402 or 0603 SMD resistor is the natural size-match companion). For DCC/AC power, add a bridge rectifier — see the AC/DCC wiring guide.

0807 vs. 0603 SMD animated LEDs: The 0807 package (2.0mm × 1.8mm) is slightly larger and easier to hand-solder than the 0603 SMD (1.6mm × 0.8mm). Both share the same electrical specs and flash rate. Choose 0807 for hand-soldering accessibility and slightly higher light output. Choose 0603 for the absolute minimum footprint on a high-density PCB.

Yes, with basic SMD soldering skills. The 0807 package (2.0mm × 1.8mm) is manageable with a fine-tip iron, flux, and thin solder wire. Magnification (loupe or magnifying lamp) helps with pad alignment. Tweezers are essential for placement. The 0807 is easier to hand-solder than the smaller 0603 package.
Yes. The internal IC controls flash timing only. A series current-limiting resistor is required. Use our LED resistor calculator. An 0402 or 0603 SMD resistor is the natural size-match companion on a PCB.
Physical size. The 0807 (2.0mm × 1.8mm) is slightly larger and easier to hand-solder. The 0603 (1.6mm × 0.8mm) is smaller and better suited for high-density PCBs. Electrically they are identical — same forward voltage, current, and resistor requirements.
Technically yes — you can solder thin magnet wire directly to the SMD pads under magnification, which is how some model railroad hobbyists install SMD LEDs inside locomotives. However, SMD components are designed for PCB mounting. If you prefer traditional wire-lead installation, use a through-hole animated LED in 1.8mm, 3mm, or 5mm instead.
SMD LEDs emit light over a wider angle (typically 120–160°) rather than the focused 15–30° beam of a clear through-hole LED. The total luminous flux is comparable, but the light is spread over a much wider area. On-axis (mcd) brightness appears lower because the light is not focused. For applications requiring a focused beam, use a through-hole LED. For wide-angle indicators and PCB-mounted status lights, SMD is the better choice.
Yes, after DC conversion. Bridge rectifier + smoothing capacitor. See the AC/DCC wiring guide.
