IR LEDs in stock now - why buying local speeds your project
Get the infrared LEDs you need today from a South African distributor that holds practical stock for university labs, maker spaces and engineering teams. We focus on availability, quick branch collection and clear specification guidance so your prototype or deployment doesn’t stall on lead times or unclear part choices.
What we keep on the shelf
Common clear-stock items include 850 nm and 940 nm LEDs in 3 mm, 5 mm and 1206 SMD packages, high-power emitter modules with integrated heat-sinking, emitter arrays for security illuminators, and matched photodiodes/receivers for simple pairings. Popular maker brands and component families are stocked; see our broader product range in Collections (Shop by Category) and browse by brand at Shop by Brand.
Quick spec callouts to check before you buy
Don’t pick a part by wavelength alone. Verify forward voltage (Vf), typical radiant intensity or radiant power, viewing angle, package type, and continuous vs pulsed current rating. If you plan to beam over distance, check radiant intensity and viewing angle first; for short-range sensor work, radiometric power and peak wavelength matter most.
Specification comparison (example)
Use the following brief table to compare three common IR LED types you might choose from stock.
| Type | Wavelength | Forward Voltage (Vf) | Typical Drive Current | Best for |
|---|---|---|---|---|
| 3 mm through-hole | 850 nm | 1.2 V | 20 mA | Prototyping, hobby sensors |
| 5 mm high-intensity | 940 nm | 1.3 V | 30-50 mA | Remote controls, longer-range emitters |
| High-power SMD/module | 850 nm | ~1.6 V (per die) | 350 mA-1 A | Illumination, security arrays |
Compatibility & accessory guidance
Pair IR LEDs with matched resistors, constant-current drivers or PWM-capable LED drivers depending on your application. For student or lab use, supply multi-packs and resistor assortments to keep builds moving. See related electronics and components in our full product index: ir-leds-in-stock-south-africa.
On-the-bench specification checks before checkout
When selecting parts from stock, confirm the datasheet values for continuous vs pulsed current so your driver matches the LED’s thermal limits. If you’re unsure, request a component pairing note or check stock in Samrand for hands-on inspection and testing.
