Vishay Intertechnology, Inc. introduced three new commercial IHLP low profile, high current inductors in the 3.3 mm by 3...

Featuring separate red, green, and blue LED chips inside the compact 3.5 mm by 2.8 mm by 1.45 mm PLCC-6 surface-mount package, the Vishay Semiconductors VLMRGB6112.. enables individual control of each chip, making it possible to realize every color within the color room defined by the gamut triangle area inside the CIE 1931 color space through color mixing.

With its wide color range, the LED released today is ideal for custom "welcome illumination" in next-generation automobiles; large-format, full-color message and video display boards; backlighting in consumer devices and appliances such as PDAs, televisions, ovens, and microwaves; and a wide range of accent and decorative lighting.

For these applications, the device utilizes high-brightness AllnGaP and InGaN technologies to deliver luminous intensity to 1800 mcd at 20 mA and features a ±60° angle of half intensity.

Providing high reliability, the Automotive Grade VLMRGB6112.. offers a wide temperature range from -40 °C to +110 °C, excellent corrosion robustness and sulfur resistance (H2S), and a UV-stable, diffused silicone casting compound for a long lifetime.

The LED is AEC-Q101-qualified, offers a Moisture Sensitivity Level (MSL) of 2, and withstands ESD voltages up to 2 kV in accordance with JESD22-A114-B. Compatible with IR reflow soldering, the device is RoHS-compliant, halogen-free, and Vishay Green.
