Buy 5mm Super Bright Red LED Clear Dome Lamp - In Stock at Communica

Quick Specification Callouts

When shopping for a 5mm clear dome super bright red LED, compare these primary specs to ensure the component fits your design and suppliers in South Africa can supply replacements quickly:

• Lens type: clear dome for wide viewing angle vs diffused for softer light.
• Forward voltage (Vf): typically ~1.8-2.2V for red LEDs; check datasheet for exact value.
• Luminous intensity: given in millicandela (mcd); super bright parts often exceed 5,000-10,000 mcd depending on measurement angle.
• Viewing angle: 20-50 degrees for narrow focused vs 60-180 degrees for wide indicators.
• Current rating: standard 5mm LEDs are rated at 20mA nominal; many projects run them at 2-10mA to extend life and reduce brightness.

Common package and mechanical notes

5mm (T-1 3/4) leaded LEDs have typical lead spacing of ~2.5mm at the epoxy base and standard axial leads for through-hole PCBs or panel mounting with bezel holders. Clear dome variants emphasise peak brightness and are preferred where visibility at distance matters.

Compatibility & Drive Calculations

To drive a 5mm red LED from a DC source safely, use a series resistor or a constant-current driver. Use the following resistor formula for a single LED in series:

R (ohms) = (Vsup - Vf) / I

Example (SA context): from a 5 V microcontroller rail, with Vf = 2.0 V and desired current I = 10 mA (0.01 A): R = (5 - 2) / 0.01 = 300 ohms. Choose the nearest standard resistor value (e.g., 300 ohm) rated for appropriate power.

Accessory Bundles and Practical Buying Tips

• Resistor packs: include assortments (220-500 ohm) for prototyping.
• LED bezels and holders: useful for panel mounting and neat finishes.
• Prototype boards & jumper kits: speed integration with microcontrollers.
• Heat and current derating: run at lower current in high-temperature enclosures to extend life.

Stock, Ordering and Local Support

Communica lists LEDs under the Semiconductors & LEDs and Prototyping collections. For small quantities, check online stock and select "Check Stock in Samrand" or your preferred branch for collection. For bulk orders, use "Request a Quote" to confirm lead times and VAT invoicing for institutional purchases (education departments and procurement teams commonly request formal quotes).

Recommended brands and ranges commonly stocked include industrial and maker-friendly manufacturers. If a particular luminous intensity or viewing angle is required, compare datasheets and use the "Compare Specs" option to match parts before ordering.

Common Troubleshooting

• LED not lighting: check polarity (long lead = anode), resistor value and supply voltage.
• Dim LEDs: reduce series resistance or increase drive current within the LED's maximum rating, or choose a higher mcd part.
• Uneven brightness across panels: ensure consistent resistor values and wiring length to avoid voltage drop over long runs.
