Blue And White PC-Board LED Indicators Offer Mounting Options

Lumex has expanded its line of PC-board indicators with two series of high-intensity blue or white LEDs in both through-hole and surface-mount technology (SMT) versions. The through-hole versions are in the SSF-LXH103xx Series, which incorporate a right-angle-mounted T3 LED whose center is raised 5.08 mm off the circuit board. The narrow, 4.6-mm width of these devices makes it easy to gang them horizontally. The blue version has a light intensity of 80 mcd at If = 20 mA, with a viewing angle of 60 deg. The white version has a light intensity of 500 mcd at If = 20 mA, with a viewing angle of 60 deg.

The SSF-LXH305xx series includes the SMT devices. They are two-piece indicators that also house a right-angle-mounted T3 LED. Unlike other SMT indicators, in which the LED must be mounted flush against the circuit board, these units position the centerline of the LED 3.5 mm. above the PCB. This gives designers the ease of installation of the SMT package and the flexibility afforded by the off-board location. These devices handle IR reflow soldering techniques and are available on standard 24-mm tape for automated insertion. The blue LED has a light intensity of 80 mcd at If = 20 mA, with a viewing angle of 60 deg. The white versions come with either clear or white diffused lenses. Intensity and viewing angles are 800 mcd and 30 deg. for the clear lens and 400 mcd and 60 deg. for the diffused lens.

AVAILABILITY

Samples of the standard-version blue and white LEDs are available from stock. Production quantities are available in two to eight weeks. PRICING

Pricing depends on model and quantity and is approximately $0.90 each in lots of 1000. FOR MORE INFORMATION
