Comprehensive guide to L-53SYD 5mm diffused dome yellow LED lamps: datasheet specs, typical uses, wiring, and local South African stock at Communica.
Explore the key specs of diffused 5mm yellow LEDs for hobby, education, and industry.
Learn wiring, resistor sizing, and troubleshooting for optimal LED performance.
Find L-53SYD LEDs, accessories, and pickup options at Communica branches.
LED lamps are at the heart of countless electronic projects, providing efficient, long-lasting light with minimal power consumption. The L-53SYD 5mm diffused dome bright yellow LED is a common through-hole LED used by South African makers, students, and technicians for indication, panel displays, signal lamps, and educational kits. Its diffused dome softens the light and enhances wide viewing, making it well-suited for dashboards, control panels, and simple status indicators where a gentle, vibrant yellow signal is required.
| Parameter | Typical Value | Units |
|---|---|---|
| LED Type | Through-hole, diffused dome | - |
| Diameter | 5 mm | mm |
| Colour/Wavelength | Yellow / 585-595 nm | nm |
| Forward Voltage (VF) | 2.0 V (typical) | V |
| Forward Current (IF) | 20 mA (recommended max) | mA |
| Brightness | 8-12 mcd | mcd |
| View Angle | 60 degrees (diffused) | degrees |
For project and procurement teams, these values ensure compatibility with common 3V/5V/12V logic circuits, microcontrollers, and PLC outputs (with correct resistor sizing).
The diffused lens on the L-53SYD scatters light for a uniform glow and less direct glare compared to clear-lens LEDs, making it popular for visible alerts in education kits and public-facing panels. The robust 5mm leaded package is easy to solder or use in breadboards, suitable for both quick prototyping and long-term installations.
(Vcc)----[Resistor]----|>----(GND)
(L-53SYD LED)Connect the anode (long lead) to the supply voltage via a current-limiting resistor. The cathode (short lead) goes to ground.
To ensure optimal brightness and safety, calculate the current-limiting resistor using Ohm's Law:
R = (VS - VF) / IF
Example: For VS = 5V (Arduino or Raspberry Pi), VF = 2.0V, desired IF = 15 mA (0.015A):
R = (5V - 2V) / 0.015A = 200Ohm
Choose nearest preferred resistor value: 220Ohm (protects the LED and ensures lifespan).
For 12V industrial signals: R = (12V - 2V) / 0.015A = 666Ohm. Choose 680Ohm or 1kOhm.
