Product Overview
Unbranded IR-LED-5mm-sl infrared emitting diode in a standard 5mm (T-1 3/4) water-clear package. Features an integrated base standoff flange and two-pin radial through-hole termination pre-trimmed for low-clearance board assemblies.
Key Features
- Package type: Standard 5mm (T-1 3/4) radial form factor
- Lens: Water-clear round epoxy dome with molded base flange
- Terminals: Dual radial leads pre-clipped for low-profile PCB placement
- Internal construction: Visible anvil and post leadframe configuration
Applications
- Soldering direct-to-board into compact optical transmitters and remote controls
- Assembling low-profile infrared beam-break triggers and object detection sensors
- Building DIY sensor arrays on custom breadboards or perforated proto-boards
Frequently Asked Questions
What mounting style do these LEDs use?
They feature through-hole leads that are pre-trimmed short, making them ready for low-profile direct PCB soldering or custom socket installation where standard lead length would otherwise need manual cutting.
How is polarity identified with the leads cut short?
Polarity is determined visually through the clear epoxy dome. The larger internal leadframe element (the anvil) connects to the cathode, while the smaller post connects to the anode. The flat spot along the molded base flange also aligns with the cathode terminal. Order more and each piece costs less - the price-break table on this page spells it out.
Pre-trimmed leads mean less bench prep and quicker placement when you are assembling tight optical circuits. Drop them in, solder them down, and let invisible light do the quiet work.
