Product Details
✓PLCC-4 SMD LED — 4-pin construction - 5 Cool White PLCC-4 (3.2x2.8mm) 4-pin SMD LEDs that handle higher current and dissipate heat through 4-pin construction — suitable for higher-output PCB designs and custom electronics
✓High-output 4-pin PLCC-4 SMD LED rated at 2300 mcd cool/clear white output through a diffused lens with a 120 degree wide viewing angle. Forward voltage is 3.0-3.2V at 20mA per chip across 3 internal chips/diodes for even, glare-free illumination at close viewing distances.
✓PLCC-4 surface-mount package measures 3.2 x 2.8mm with four solder pads on the underside, allowing reflow assembly onto custom PCBs. Four-pin construction routes drive current and heat across twice the pad area of a 2-pin SMD, improving thermal dissipation and supporting higher sustained current on properly designed copper pours.
✓Polarity and resistor reference - Surface-mount LEDs are polarity-sensitive: cathode is marked on the package underside per the datasheet pad map. For 20mA drive current with a 3.0-3.2V LED, use a series resistor of 100Ω 1/4W on 5V, 300Ω 1/4W on 9V, 470Ω 1/4W on 12V, or 620Ω 1/2W on 15V.
✓Cool white 2300 mcd diffused output through a 120 degree viewing angle suits custom PCB design where higher per-emitter brightness and improved thermal headroom matter: instrument cluster backlighting, gauge panel illumination, compact indicator arrays, status panels, and higher-output SMD applications needing better heat dissipation than standard 2-pin chips.
