QBLP651-S is listed in the LED Indication - Discrete range at ChipApex. The manufacturer field lists QT Brightek (QTB). Its product description is LED RED CLEAR 1206 SMD. Review the specifications below when checking this part for your BOM.
The QBLP651-S is a surface-mount indicator LED manufactured by QT Brightek (QTB), belonging to the QBLP651 series. It emits blue light with a dominant wavelength of 470nm and features a clear, round lens with a flat top design. The component operates at a typical forward voltage of 3V and has a maximum DC forward current rating of 20mA. It provides a minimum luminous intensity of 80mcd when tested at 20mA. The device utilizes a 1206 (3216 metric) package with dimensions of 3.00mm in length, 1.50mm in width, and a maximum height of 1.40mm. It offers a viewing angle of 40 degrees and is designed for top-view orientation.
Verify the specific suffix against official QT Brightek documentation to confirm exact optical characteristics and binning requirements. Ensure that the selected variant matches the required forward voltage and luminous intensity specifications for the target application. Confirm RoHS compliance status through the manufacturer's declaration of conformity prior to procurement.
Select this component based on its 1206 surface-mount footprint and standard 40-degree viewing angle. Consider the 3V forward voltage drop and 20mA test current requirements for driver circuit design. Evaluate the 80mcd minimum luminous intensity against ambient lighting conditions to ensure adequate visibility for the intended indicator function.
The QBLP651-S is part of the QBLP651 family of surface-mount LEDs from QT Brightek. This series includes various colors and configurations optimized for compact electronic designs. The 1206 package size allows for high-density PCB layouts while maintaining reliable thermal performance and mechanical stability during assembly processes.
