LED Features 120° Viewing Angle And Luminous Intensity To 120 mcd
The 1104B top-view surface-mount light-emitting diode features a 120° viewing angle. Depending on color, the LED offers a typical luminous intensity of up to 120 mcd. The series comes in colors including red, orange, yellow, green, blue-green, and blue. This LED has an operating-temperature range of 40°C to 100°C, making it suitable for automotive and portable computer applications.

Other features of the device include 80- to 125-mW power dissipation, 20- to 50-mA forward current, 50- to 150-mA peak forward current, and 4- to 5-V reverse voltage. Also, derating is 0.5 to 0.75 mA/°C. In a standard PLCC-2 package, the device has a 2.2- by 2.8-mm footprint. It is available on EIAJ standard ETX-7001 reels. With a peak temperature exposure of 240°C for up to five seconds, this LED is compatible with both dip and reflow soldering equipment.

Surface-Mount LEDs Include Built-In Domed Lenses
The LXL1307 and LXL1209 series of surface-mount technology (SMT) LEDs feature built-in domed lenses on top of a flat-bottomed carrier. Both devices focus light to a 50° angle of emission, effectively increasing light intensity as seen by the observer. According to the company, these LEDs are suited for display and backlighting applications and for status or circuit fault indicators.

The LXL1307 series is packaged on a chip carrier with a 3.2- by 1.6-mm footprint. It has a high point of 1.8 mm above the mounting plane. The LXL1209 series is packed on a chip carrier with a 3.2- by 2.4-mm footprint and 2.6-mm high point. On-axis light intensities as bright as 1500 mcd are provided by AlInGaP, GaAlAs, and InGaN/SiC chips in both series. Available colors include Super Intensity Red, Super Orange, Super Red, Super Yellow, and Ultra Super Blue. Both series are available in taped reels compatible with automatic insertion equipment.

In quantities of 1000, the Super Red LXL1307 typically costs $0.05 each.
