The WL-STSW SMT Sideview Waterclear Phototransistor LEDs have a 1104 standard size and a wide spectral range of 400nm to 1100nm. The WL-STSW is a counterpart to the WL-SISW IR LEDs due to the same design and wavelength range. The standard design makes the WL-STSW easily implemented into existing circuit diagrams.
WL-STRB Reverse Mount Black Phototransistor LEDs are characterized by a 1206 chip package size and a daylight-blocking filter. The WL-STRB allows easy integration of existing circuit diagrams and is excellent in combination with the WL-SIRW IR LED series.
The WL-STCW SMT Waterclear and WL-STCB SMT Black Phototransistor LEDs have a chip-top view in a miniature SMT package. The WL-STCW is spectrally matched to visible and infrared emitting diodes. The WL-STCB is developed with a daylight filter and is only used for suitable infrared applications.
The WL-STTW SMT Top Waterclear and WL-STTB SMT Top Black Phototransistor LEDs offer a PLCC-2 3528 housing. The devices are available in black silicone (WL-STTB) and without a transparent silicone daylight filter (WL-STTW). The WL-STTW and the WL-STTB are ideal in combination with the WL-SITW IR LED series due to the design and the wavelength range.
